The meta you linked makes a great point overall but doesn't actually have anything really actionable other than 'use the game's official numbering as the base tag', which is probably why the tag synonyms didn't get created.
You can suggest synonyms, but you need 2500 rep and some upvotes within each tag if you're going to suggest a synonym:
Users with this privilege and a total answer score (total upvotes minus total downvotes) of 5 or more on the tag, can suggest tag synonyms. Users with a total answer score of 5 or more on the tag, can vote for tag synonyms...
Suggestions will be automatically approved when they reach a score of 4, and automatically deleted when they reach a score of -2.
Otherwise if you would like us to create some synonyms, list out all the tags and which synonyms you believe would help (perhaps as an answer?) - that way the community can discuss each in turn and vote on it. If you get a majority agreement about the usefulness of the synonyms, we can look at creating them.
