ZealOS is like the 1040EZ tax form compared to the full 1040 form. Obviously, it is simpler. If you allow mission creep, pretty soon the 1040EZ looks just like the 1040 and the messed-up 1040EZ has no purpose.
The Commodore 64 had a file system that was simple enough for peers in Terry's generation to enjoy the thrill of knowing exactly what is going on at the hardware level and writing fun projects to access it.
The primary design criteria is simplicity. If it is simple enough for only 100,000 people to learn, lets try to make it simpler so that 1 million can learn it.
Obviously, we don't do bad block tables, or redundant FATs.
We use the simplest possible technique, a contiguous-file-only allocation bitmap, not $LK,"Block Chains",A="FI:::/Doc/BlkChain.DD"$ or FAT tables.
You can be a good toy or you can be a good professional tool, but not both. ZealOS's file manager will start too slowly once a few thousand files exist because the file manager makes a list of all files on start-up.
Do not have more than a few thousand files or the file manager will not function.
You are encouraged to keep your entire drive limited to, maybe, 100 Meg of files because you are suppoosed to operate as a kayak instead of a Titanic. If you do this, backing-up will be only a minute or so and you should do it at least once a day.
Third party software should be run from ISO files or CD/DVDs directly, without installing to hard drive.
Multimedia graphics and sound is, basically, forbidden. If you ignore this, all hell will break loose because memory will fragment with large files and the original vision of kayak hard-drive back-ups won't work.

If a feature cannot be made to work correctly and consistently, professional companies usually remove the feature. Because PC hardware is so diverse, getting things to work on all people's computers is really difficult. For one thing, you practically have to own all the different hardware to write drivers for it. If a company wanted to sell a PC operating system, they would offer a warranty and, therefore, could not get away with amateur behavior.

The PCI bus interface is what modern hardware uses. Before PCI, life was simple and devices used I/O ports. After studying $LK,"PCI Interrupts",A="FI:::/Demo/Lectures/PCIInterrupts.ZC"$ and attempting to do a HDAudio driver, Terry Davis came to realize that modern PCI devices require ten times more code and he cannot even come close to making them work on everyone's machine because with PCI devices there are several models to worry about, unlike with the older ISA bus devices which can be done with one driver.

We use the $LK,"PIT timer",A="MN:TimerInit"$ and $LK,"PIC Interrupt Controller",A="MN:IntPICInit"$. We use IRQ0 for timer, IRQ1 for keyboard, and IRQ12 for mouse. If IRQ12 is not firing, we are able to poll the mouse.
In the CPU department, ZealOS has state of the art 64-bit $LK,"long mode",A="FI:::/Kernel/KStart64.ZC"$ with $LK,"multicore",A="FI:::/Kernel/MultiProc.ZC"$ support. We use the $LK,"APIC",A="MN:MPAPICInit"$ and start-up $LK,"multicore",A="MN:Core0StartMP"$ operation.

Adding a USB driver would be really ugly with UHCI, EHCI, OHCI, USB1, USB2, USB3, ICH6, ICH7, ICH8, ICH9, ICH10, ICH11, ICH12, boot mode and regular mode for keyboard/mouse and a diversity of HID reports. It's hopeless. It could never offer anything but crappy, limited support and it would just add a ton of crappy code that mostly didn't work. What would ZealOS gain? Nothing. A keyboard or mouse would not be improved. Solid State USB drives would be nice, but it's not going to happen.

The same story is basically true for GPUs and audio drivers. If you attempt multimedia, everything will break because memory will get fragmented with huge multimedia files.
UEFI is pointless. If ZealOS is forced to run in VMware, QEMU or VirtualBox, they will always support non-UEFI mode. Without working, native hard drive and CD/DVD drivers, you can't get very far with UEFI on a native install, not to mention SecureBoot. UEFI is, first of all, redundant. If non-UEFI works in a virtual machine, supporting UEFI would only be redundant, ugly nasty code. The compiler does not create an ELF or PE format. We would have to ruin the beauty of the compiler.
