I hope not.
I remember the time when Apple switched over to x86.
Every developer (including me) had to do extra stuff to support both architectures (PPC, x86) resulting in extra large binaries.
Now Apple has managed so that there is only one architecture left to support on the desktop, which is x86_64.
Switching over to ARM returns all the shit.
Yes, Xcode helps a lot in building multi-arch binaries. But there are a large number of ports which are makefile based that need to be tweaked to support more architectures.
