Feature request (regression): tag apps that require the Google Services Framework

Description

Especially when I don't have microG or have it partly disabled, it is important to me to be able to know whether an app depends on the GSF (GMS, Google Play Services, however we want to call it). I believe Aurora Store 3.x provided this as a tag, and that was useful to me.

I would like this tagging to be re-added if possible; I think it was also possible to dynamically filter by tag, but I think dynamic search filtering is not yet available in v4. In general, though, it would be nice to be able to search for a combination of apps that don't have ads and/or don't require GSF.
