I was just playing a bit more and it turns out that `/usr/lib/python3.9/sysconfig.py` does not include changes from `patches/sysconfig-debian-schemes.diff` at all! I've verified I do have Debian Bullseye :), file is proided by `libpython3.9-minimal:amd64:`. sysconfig-debian-schemes.diff is also in `patches/series`. I do not know what to think at this point..
