Yes, I've changed that.
Packages in Debian should use Python 3. New packages must
use Python 3 from the initial upload, new upstream versions
for existing packages must use Python 3. If Python 2 is still
supported in Bullseye, selected packages may continue using
Python 2 until Python 3 support is available. Please discuss
all use of Python 2 on the debian-python mailing list before
uploading.

OK, replaced the paragraph.

Done.

Actually, that's a good catch. I was mixing up the defaults package
with the general advice on python3 migration to not remove
python-foo-doc just to rename it to python3-foo-doc.
Removing the defaults package python-doc seems right to me. I've
updated that paragraph.
