Maybe also for action=expandtemplates and [[Special:ExpandTemplates]]
Change 168669 had a related patch set uploaded by Umherirrender: Add preprocessflags to revisions/parse/expandtemplates https://gerrit.wikimedia.org/r/168669
The patch does not include [[Special:ExpandTemplates]], maybe create a new bug, if that should also have the flag.
