I've seen at least two packages in the last three month. It is mostly test data. It actually seems to be common there, but usually it is not a problem when we can use pypi. I don't know how common it is in other areas.
I also don't know if we have any other phase where these kind of permission problems can lead to errors, but it would be nice, if we could check that, and fix all of them with one commit. It should be based on core-updates, of course, and not in this round, I guess. Ludo’. >
