Honestly I've only ever played it single player or with 2 players. So yes, it's 100% playable under all conditions that I've been able to test. There are plenty of games with unacceptable performance on my machines; do I get to call all of them alpha-quality?
My objection was not related to 0AD versioning their releases as "alpha". That's absolutely fine by me! My objection was related to you describing 0AD with words "It is 100% playable and has been for years". Clearly it has not been 100% playable for years!
