On a technical note, there was also an inter-dependency with the AMP
implementation, as both needed many modifications in the same places. So
Austin went first with the AMP, and as soon as that was done (which
turned out to be quite more tricky and took much longer than
anticipated), I started addressing the BBP implementation based on the
post-AMP state (while trying to get this done quickly enough not cause
too many merge-conflicts with other commits that were being pushed to
HEAD as well as `base`-patches being submitted to Phabricator...)
