I'd like to request that it be possible for users (or perhaps a limited subset of users) to be able to use javascript on loginwiki, without needing to manually copy-paste it into their browsers each time. For example, I have a script that filters Special:Log/newusers to only users with any global edits, and shows which wikis those users were created on, which I use to find spambots.
Prior history:
GlobalCssJs is disabled on loginwiki, and has been since initial deployment at T59891
T102254: Allow a script to work on login.wikimedia.org
wgAllowUserJs is false for loginwiki
