We certainly can if we want to.

Our formal deprecation policy codifies our compromise between the need
to evolve QEMU and the need of its users for stable external interfaces.

"Compiles on host X" is also a need, but it's a different one.
Evidence: "Supported build platforms" has its own appendix, separate
from "Deprecated features".  It's mum on 32-bit hosts.

I'm not saying we *should* drop 32-bit hosts immediately.  Only that the
feature deprecation policy does not apply.

Is QEMU still useful on 32-bit hosts?  Honest question!
