I have some huge reservations here.
Naming is everything, and we could not simply give it a “new label”, we would need a new column on the user table and to migrate every tl4 check internally to use the new name and define new UI for this. (assigning it on admin page)
These kind of changes scare me, have huge potential for regression and would require a non-trivial amount of work to implement.
So let me point this back at you 
Do you think it is worth “3 weeks” of dev time to make this naming change?
