Or we can let players form clans themselves, like what happens in most FPS games.

Sometimes 2 or 3 players want to be in the same team because they are all on discord or because they are siblings.

Team ratings would motivate clan formation.

I disagree with some points:
1300 minimum (league could also be open for all skill levels)
100 games seems too much, could also be 20 or something

limited to 3 months might also be to complicated, you could remove that

0AD is free, so having one account should also be free.

It's not necessary to let rating decline, as players can keep their skill level over a long time even when they dont play rated. Why not just treat ratings as Lichess does? If someone does not play rated, the uncertainty of the rating increases. After a weak or so, the player gets removed from leaderbords, and when uncertainty reaches a certain level, the rating gets marked with a question mark, so you can see that its very uncertain. Playing rated reduces the uncertainty.

+1 for team leagues and rated team games

Theoretically the 1v1 rating and the team rating of each account could also be identically. I think Age of Mythology does it like that. And theoretically its not necessary to register teams for rated team games. Just make sure that your team mates are no rage quitters if you play rated....

Agree with your suggestions.

Players form multiple accounts and then dupe the TGs as poorly rated players while actually they are smurfs leading to imbalance, spoiling the fun. 

Even now  most hosts do not allow poorly rated players to play with them. So, agree that we could have multiple leagues for multiple rating levels. But it is important that ratings are assigned properly and there is a value to it. Players should take pride in their ratings and it should be difficult to earn.

The objective is to make games more fun. I would say 50% of games end poorly because of imbalance. Also TG is a different skill compared to 1v1 and static team ratings will help players develop those skills.

The uncertainty in ratings is a good idea and could be used as Lichess does.

Team registrations

Team registrations would allow development of leagues and a lot of fun.

A lot of known players play 0ad in teams everyday. In fact, most of the fun games are played in teams. By allowing players to register in teams with a condition that the players in the team each must have at least 1300 ratings and having played at least 100 1v1 games with known players, across 3 months, would reduce duplicate account creation.

There will be a value to maintain your 1v1 ratings and a price  on account names. This would allow development of good teams and balanced, fun multiplayer games.

Team ratings

When team registrations are curated, the games would be played without disruption, rage quits, etc. This would give importance to team ratings. An algorithm must be developed to assign team ratings. In particular, ratings must decline if the team does not play for long time. (This should be the case even with 1v1 games.)
