This seems to have been done by the "let things break" approach that 
isn't allowed in Debian, e.g. they can no longer build python-matplotlib:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=934870
https://launchpad.net/ubuntu/+source/matplotlib2/2.2.4-2/+build/17968574

pandas is part of the big tangle discussed in
https://lists.debian.org/debian-python/2019/10/msg00092.html

I haven't yet had time to investigate whether it can be removed from 
that tangle (by e.g. dropping Build-Depends and accepting skipped tests).

There's also the possibility that upgrading pandas to 0.25 will break 
API enough to break some reverse dependencies.

I intend to look into this tomorrow.
