from the ci perspective, that's both pointless (because the grouping can
be achieved temporally by just staging the changes at the same time) and
insufficient (because the system currently just won't do atomic

if you want to use the topic name as the label that has been originally
proposed, regardless of the CI system, then there is nothing to fix:
the ability to set the topic has been available forever (it just does
not have any magic effect on integration).
the problem with such "soft-labeling" is of course that it's laborious
and terribly easy to mess up.

fwiw, openstack's zuul recognizes explicit dependency markers in commit
message footers, which is kind of a middle ground (it's formalized, so
it can be checked). i'm not a particular fan of their gerrit<=>ci
integration approach to start with, though.
