per elwiki community consensus please create 'rollbacker' usergroup right.
New usergroup has the following rights:
Not create redirects from source pages when moving pages (suppressredirect)
Quickly rollback the edits of the last user who edited a particular page (rollback)
Should be able to be granted/revoked by administrators.
There is an ongoing discussion of local names(rollbacker on Greek language), but not a discussion of right creation.
The consensus on usergroup creation was reached.
I received a request from admin to submit this ticket, so I submit it. This is the same as T255569.
Thank you for your work.
