I think it would be nice if you added relevant tests directly in the
commits that introduce the new completions. E.g. add a test for the
bisect terms in the same commit where you introduce the completion for
it.

Like that you can easily add tests one by one, which decreases the
review load. Also, it serves to demonstrate both that the functionality
works and helps the reviewer to understand better what exactly you are
adding by having a nice example.
