But I do question whether we need to support 64-bit guests on 32-bit
hosts at all.
Retaining 32-bit on 32-bit allows arm32 to emulate i686, which I
suspect, but have no proof, is the limit of what users actually want.
I presume you implicitly restrict that to user emulation, right?
WRT i686, if your example is "i686 useremu on non-x86 embedde router"
then any 32-bit host is potentially interested, not only arm32.
I remember being able to run armhf binaries on armel hosts (and vice
versa) was useful 7 years ago. Today I have no clue, we could poll the
community and some distributions.
