I expected exactly this proposal when Apple announced the 64-bit
only iOS 11 near 3 months ago. ( I should have bet. :) )
I can understand that 32-bit is only an unnecessary barrier
for you and you don't want to bear the maintenance cost of it
when there isn't a significant amount of contributors for
maintaining and active developing 32-bit backends.
Maybe it will be hard to say good bye to 32-bit architecutres
for many people, but please, it's 2017 now, the first ARMv8 SoC
is out 4 years ago, the first AMD64 CPU is out 14 years ago.
