I prefer the latter option on general principles. However, in either case, I found that I needed to temporarily disable building black with mypyc (by commenting out `export HATCH_BUILD_HOOKS_ENABLE=1` in debian/rules), because both the patched 25.1.0 and black 25.9.0 have many test failures with mypy 1.18.2 in testing/unstable, to the extent that I suspect the resulting package would be broken. I see somebody seems to have started working on upgrading to a new mypy upstream (https://github.com/psf/black/pull/4749), but the commits so far don't seem relevant to this. I haven't exhaustively checked the upstream main branch, but I don't immediately see anything relevant there either. Michael, do you think it would be acceptable to disable building with mypyc for now, or do you have any better ideas? Let me know if you need me to push my work in progress somewhere.
I think a newer version of black (and fixing this bug) is more important than black being compiled with mypyc, so a temporary commenting out of HATCH_BUILD_HOOKS_ENABLE is fine by me. Thank you!
