Comment:

 Hello

 The code changes are mostly small, even when it took some time to make it
 work
 and modify all the templates on the way. I don't think it needs a
 changelog
 entry, because it's an internal change only.

 I also noticed some of the find variants are not used except for the
 tests.
 Should we care about that?
