My mistake, then.  I should have waited for you to speak.  I
apologize.

There is no good technical reason for AArch64 to merge with AArch32,
and IMO it would create a mess.  AArch64 is a clean-sheet design which
shares some of its DNA with AArch32, but that is all.  It's not like
x86-64, which is a 64-bit extension of x86.

I guess not, if a C2 port is forthcoming.
