First off, I'm sorry if creating a new task was unnecessary. But I really didn't want to risk necroposting a thread https://phabricator.wikimedia.org/T75414 that's almost old enough to go to school.

I just wanted to ask a question regarding this comment on the said task:

I've checked the user class, and proxyunbannable is never checked for sysops since they have ipblock-exempt.
All usergroups with proxyunbannable already have ipblock-exempt.
So this can be removed from core without removing proxy blocking.

I'm a bit confused as to what that statement means. Does it mean that the abilities that were included with the (proxyunbannable) right are also included in the (ipblock-exempt)? Or does it mean that all the usergroups with the (proxyunbannable) right at the time also had the (ipblock-exempt) right?
