Differences in outputs of various wfs are due to other PRs tested with this one and not yet in the baseline (e.g. #40464 and #40445). PR tests are not sensitive to this PR, except for checking python syntax.

In the future, we could improve this function adding checks (e.g. on existence of PrescaleService in the process), and supporting wildcards/regex for path names.

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)
