Background
Users who have the right to reveal IPs of temporary users globally (or on multiple wikis) don't want to check a preference on each new wiki they visit for patrolling work.
We need a global preference that works like the local preference implemented in T326736: Create preference for viewing IP addresses used by temporary accounts.
Details
It would be nice to replace the local preference with a global preference, rather than introducing a global preference in addition to the local preference. Anyone accepting the preference would be accepting the agreement for all our wikis.
Advantages of this:
- For users with the right to reveal IP on more than one wiki, they only need to accept the preference once
- For users who only have the right to reveal IP on one wiki, once they have accepted the global agreement, they do not need to sign it again if they gain the right on another wiki
- We will not need to determine what should happen if the global and local preferences don't match. The existence of a global and local preference led to complexity during the IPInfo project: T298977
