Python 3.5 will be EOL three months from now. The warning hopefully prevents any dependencies on Python 3.5 sneaking into release 20.09.
External dependencies (e.g. in NUR) get a visible notification and have enough time to migrate.
Yey, it trips ofborg, but there should be no more references to python35 once #89755 is merged, so ofborg should not evaluate this far in any other PR. Don' t know about Hydra, but local evaluations should not fail as it only prints the warning, pretty much as with the mlocate service.
