Most of the problem that requirements is trying to solve is related to
upper-constraints, blocking new releases. And this upper constraints are
used in most jobs, preventing most failure that are seen in gates. It
would have "covered" the pbr issue.

What I want to stop here, is the automatic push of blacklisting/capping
of stuff to *everything* in OpenStack as soon as one project have a
problem with something.

Agreed, I'm not suggesting to revert everything. Just the automatic push
of random requirements limits and binding to Oslo. And other projects if
you like, we don't do it for a good year anymore in Telemetry, and again
here we saw 0 breakage due to that change. Just more easyness to
install stuff.
