Apple Intel hardware is AMD64 ISA :-)

The same that is being done with MorphOS on old G5 and old Radeon graphics, which MorphOS can even less utilize the power of (SMP, 64-bit, UVD etc.). MorphOS on AMD64/x64 is supposed to be 64-bit and support SMP, at least.

Of course, there is objectively nothing that can be done better on MorphOS compared to Linux/Windows. That's not the point of it anyway. MorphOS isn't meant for the average Linux/Windows user, but for users who want to have fun doing computing an Amiga-ish way. Therefore, it's mostly a subjective and emotional matter. MorphOS doesn't get more usable just because it runs on less capable hardware.
