While it would be prudent to have the uninstaller clean up, this is a losing battle. It's basically become normalized that any package can and will overwrite resolv.conf at any time without necessarily clean up afterwards. It's seen as ephemeral. I find it kind of baffling that as an IT contractor you've managed to go months without changing it since (: Someone else mentioned making it immutable, which is not a bad idea if only editing it manually is what you want. Next step if you still want it dynamic would making it owned by the designated user of the process making the changes you actually want (e.g. NetworkManager/systemd-networkd/netctl/whathaveyou).
