Thanks, @dcavins! Functionality looks good to me. 7263.diff​ cleans up the documentation a little, and adds a note to each docblock about how the returned values are from the "taxonomy site", not necessarily the current site. cc @offereins

If you're good with the language, then the patch looks good to go.

In 11118:

Add multisite-aware wrapper for get_objects_in_term().

Add wrapper functions for working with BuddyPress taxonomies via
get_objects_in_term(). When working with BuddyPress objects like
users, we need to be sure that we’re referring to the taxonomies and
terms for the site on the network where the relevant taxonomy is
registered.

Props dcavins, boonebgorges, offereins.

See #7263.
