Might be.  At present I vote we cross the ARM bridge when we get there.  I'm uncomfortable asserting anything about how ARM behaves without testing it first.  If ARM32 and X86 have notable similarities and ARM64 and X64 have notable similarities then I think it warrants coming up with some abstractions for them.
