Of course, in order to be fully usable, the HPy universal ABI will need special

It's totally possible, it's just that none of the existing tools will
automatically generate the tags you need. (These are most critical in
the filename itself, and also appear in 1-2 bits of metadata that
currently are unused AFAIK.)
Basically, instead of just "cp310" (or "abi3", etc.), you'll want to use
dots to separate each supported version ("cp38.cp39.cp310"). That will
match the wheel to any of those versions.
You can even do the same with OS platforms if you prefer fewer/bigger
wheels over more platform-specific ones.
Python on all platforms since IIRC 3.6 (maybe 3.5?) also have version
and platform-specific tags in extension modules. These do not support
combining tags as in wheels (and unfortunately do not match wheel tags
at all), but do allow you to have version/platform-specific
.pyd/.dylib/.so files in a single wheel. Again, it's just that none of
the current build backends will help you do it.
Cheers,
Steve
