The problem is not with other packages importing imp (which need to
be fixed in such a case), rather that pyximport (in
cython/cython-legacy) imports imp.  So it's cython that needs to be
patched.

I'm wondering what the provisional timescale for cython 3.0.x is?
Should I just leave my package with an autopkgtest failure until
cython 3.0.x is in unstable or ideally testing?  That's why I was
thinking of also patching cython in the short term until we are ready
for cython 3.0.x to enter unstable.

Best wishes,
