I had a very quick look at the packaged cython3-legacy.  One could
change the name of the module to Cython_legacy or probably better,
Cython0, and cython.py to cython0.py, pyximport to pyximport0.  Just a
handful of changes would be needed, I'm guessing.  Then it would be
co-installable with Cython 3.x, and any packages that actually need
cython3-legacy rather than Cython 3.x would have to be patched to call
the legacy version.  It's probably easier to just patch them for
Cython 3.x ;-)

Best wishes,
