I agree with you in theory (and practice, for I boot to plain DOS usually to get down to REAL work), but the reason these myriad kludges and hacks are appealing is simply because of M$oft's artificial limitations / abandonment of NTVDM for no good reason. And by extension, the disabling of "full screen mode" in 64-bit Windows is maddening. Lack of driver support for this simple task is a ridiculous excuse. Fullscreen mode was *intentionally* buried, for obscure and unfair reasons. We tinker, and try to get it to work, simply for the intellectual exercise -- because the problem is "there" and we DOS users are tinkerers back from the earliest days of bare metal and 8-bit days.

But it would save a lot of time to be able to run, in two seconds some simple, beloved DOS programs via NTVDM rather than having to reboot, and reconfigure BIOS into Legacy mode, enable legacy boot of USB devices, disable wifi, EFI, etc all to recover as much DOS memory from within BIOS options as possible. For enabling these BIOS options on "modern" systems, for some reason deducts from the low 640k pool of system memory available!
