> One potential advantage of not being in global-requirements.txt is that
> our unit tests and functional tests could actually test the same code. As
> things stand today, our unit tests in projects that depend on
> tripleo-common are pinned to the version in global-requirements.txt, while
> our functional tests currently run with tripleo-common from master (or
> included depends-on).
> The changes needed would be (aiui):
> - Remove tripleo repos from projects.txt
> - Remove check-requirements jobs from those same repos
> - Remove tripleo-common from global-requirements.txt
> I think it's fine as long as we manage the project requirements properly
and ensure that we don't bump to some broken library versions (Tripleo CI
may or may not catch those but other projects CIs possibly can), as we sync
those requirements to rdo spec files regularly.

> I think we should also plan to backport these changes to Wallaby.
> Let me know any concerns or feedback, or anything I might be overlooking.
