I am not sure if Lucas is on this list and reading your feedback, but
AFAIK the trends.debian.net is based off Lintian data and thus limited
in accuracy. A more accurate system would use the vcswatch table in
UDD.

Still, I think having stats about CI file usage in packages is
interesting. If we do a campaign to have people fix their Salsa CI
from red to green, we are likely to see more people switch to using an
actual debian/salsa-ci.yml file. We don't have stats currently AFAIK
on how many uses Salsa CI without using an explicit file (i.e.
directly via config).

This is what the tag says:
https://salsa.debian.org/lintian/lintian/-/blob/master/tags/u/uses-gbp-conf.tag

It will miss gbp usage in cases where there is no file, and indeed
there are pacakges that have a gbp.conf only to use a single operation
from gbp without using for the full package lifecycle.
