Starting from half a month ago CI regressions are de-facto release blockers.

The way forward in cases like these is for the package that originally
cuased the breakage (i.e. numpy) to declare a versioned Breaks on the
borken and now fixed package (i.e. astropy (<< 3.1-1)).  This way
britney and debci will know they have to test numpy and astropy
together, and will be able to correctly migrate to testing at the same
time, and properly avoid a situation when two incompatible packages
are installed.
Maybe you could open a bug on numpy to get the maintainer to add the breaks.

BTW, that numpy upload also blocked our effort to remove Python 3.6
from buster...

I don't understand this, I don't see any python2-related issue right
now.  Could you please expand?
