When you stop licensing a feature, there could be all sorts of cruft in the VCS that is otherwise challenging to remove using normal Gearset tools.

Example: We stopped licensing LiveAgent but our VCS is full of references to LiveChatTranscript and other CustomObjects used by this feature. This is particularly apparent with sub-elements of Profile

It would be cool if Gearset repo cleaner could detect when standard objects no longer available in the source org of the compare would be considered as deleted and all refs to those standard objects would be repo-cleaned.
