Holding all packages containing mailman3 and also all packages containing django produces a (mostly) working mailman installation:
dpkg -l | awk '$2 ~ /mailman/ {print $2}' | xargs apt-mark hold
dpkg -l | awk '$2 ~ /django/ {print $2}' | xargs apt-mark hold
[ ... do upgrade ... ]
sed -i 's/from collections import/from collections.abc import/' /usr/lib/
service mailman3-web restart
=> so this does seem to prove that the issue is that indeed the mailman3-web included with jammy is incomptible with previous mailman3. So supplying that elusive mailman3 package in jammy is indeed direly needed
