Comment (by jeremyfelt):

 In [changeset:"37326"]:
 {{{
 #!CommitTicketReference repository="" revision="37326"
 Multisite: Add the `pre_get_blogs_of_user` filter

 This allows a plugin to short circuit `get_blogs_of_user()` in cases where
 the default behavior of the function is unnecessary or slow. (e.g. A user
 is a member of thousands of sites.)

 Props jsternberg.
 See #31746, Fixes #36707.
