Both of those words (community and comms) have common meanings that are adjacent but distinct in important ways from the Lemmy jargon meaning. That makes them confusing and awkward to use; what if you want to talk about the Lemmy community at large or some subset of it? You would have to go way out of your way to make sure all ambiguity is removed that you might be talking about a “community” as in the subreddit equivalent. Comms is not as bad in this way I guess.
