Are you genuinely advocating replacing the BIOS with something other
than UEFI purely to avoid having to have any sort of consistency with
Apple products? That's bonkers.
The fact that Apple have been using UEFI for a while is not a reason to
not use it; it's a reason *to* use it because it means somebody else
has already gone through the initial implementation and found all (or
most) of the problems, and that there's some degree of standardisation.

Nobody's going to not switch to UEFI if it becomes reasonable to;
BIOSes are, in general, rubbish. The closest they appear to have had to
development since about 1986 is the addition of support for USB devices.
Machines frequently spend longer in the BIOS than booting the kernel.
