I think concerns about how Apple will handle the transition can generally be addressed by the relatively smooth transition from PPC to Intel. Apple has literally done this before.

6502 -> 68k in 1984 via hard-cutover [edit: see cestith's reply, there's more to this story than I knew]
68k -> PPC in 1994 via emulation
PPC -> x86 in 2006 via Rosetta JIT translation
x86 -> ARM in 2020 via Rosetta 2 static recompilation
You could even argue the transition from Mac OS 9 to Mac OS X was a transition of similar magnitude (although solely on PowerPC processors), with Classic Environment running a full Mac OS 9 instance [1]
