We often use expressions like user_editcount < 10 in order to apply a filter only to new accounts. Such a filter can disturb the work of globally active users who don't have enough edits on the wiki in concern. Something like user_global_editcount would allow admins to choose to exempt globally established users.

See for example https://ja.wiktionary.org/w/index.php?title=%E7%89%B9%E5%88%A5:%E4%B8%8D%E6%AD%A3%E5%88%A9%E7%94%A8%E8%A8%98%E9%8C%B2&wpSearchUser=Johan+%28WMF%29 - where @Johan's edit were prevented by a filter which was supposed to stop a long term abuse known to use new accounts.
I -2'd the patch as the current implementation of fetching global user edit count is too slow. I think the options we have to move forward are:
- Make fetching global user edit count faster
- Implement some kind of global autoconfirmed, which would fix the problem in the original report.
I think the second one is probably easier.
