While it's true that amd64/x86_64 has been around long enough to not have to
care (much) about its 32-bit counterpart; the same cannot be said about ARM.
It would be great to be able to say that 32-bit ARM is well dead, but we are
not there yet.

If we take x86_64 as an example, it has been “only” 10 years since the last
new 32-bit CPU was announced and until 3-4 years ago it wasn't uncommon to
see plently of people running 32-bit userlands. If things unroll in a similar
way in the ARM arena, I would expect good 32-bit ARM support being relevant
at least for another 3-4 years before the need starts to fade away.

If something, I think it may make more sense to remove 32-bit x86 support,
and have the 32-bit ARM support around for some more time.

Cheers,
