The situation was different back then, as there was no direct 'needs'
relation between the jobs.

This is also addressing a different issue, which I better understand
now. The filtering based on file names is unreliable when combined
with git pushes. Gitlab looks at the files modified in the delta beween
what is pushed as what already exists on the remote branch. So if you
push 3 changes to a branch, and then push another 2 changes later,
files modified by the first 3 changes won't be considered by the filter
rules, leading to unexpected execution behaviour.

Essentially filtering based on filename is only sane when used with
merge requests, not pushes, because a merge request has a well defined
base commit against which file changes are evaluated.

Daniel
