Synonymizer

People with this role can vote on tag synonyms for any tag with less than N questions, even if they don't have the required score.

Currently, only users with a specific amount of reputation can vote to create synonyms. If synonyms for other tags should be created, moderators need to do that. I propose a role given to users who are experienced with synonyms and tags in general (e.g. similar to a tag badge on synonym-request on the meta site but also counting questions?). This role would allow them to vote for synonyms on tags.

This would not allow them to single-handly create tag synonyms, it would still be subject to voting.

Moderators should be able to remove this role from users and also be able to revert synonymisation from tags (if they cannot already).

The maximum number of questions (N) is to be determined. Alternatively, there could be a limitation on total views on questions with this tag or a specific number of users
