Name for the larger EA+adjacent ecosystem?

Why not just call it the EA-adjacent ecosystem? I think there are lots of communities that intersect with EA, and it would probably be difficult to make one acronym that includes all of these communities.

Maybe the "PEARL communities"? (Progress studies, effective altruism, rationality and longtermism)?

Could you say a little more about the context(s) where a name seems useful?

(I think it's often easier to think through what's wanted from a name when you understand the use case, and sometimes when you try to do this you realise it was a slightly different thing that you really wanted to name anyway.)

I think EA and Rationality are fine.

How would you define longtermism so that it isn't pretty much by definition EA? Like longtermism that isn't necessarily primarily motivated by consequences for people in the future? I think GPI may have explored some such views, but I think it's close enough to EA that we don't need a new term.

If we're including progress studies, why not international development, global health, AI safety, biosecurity, nuclear security, social movements, animal ethics, vegan studies, conflict and peace studies, transhumanism, futurism, philosophy of mind, etc.? Is progress studies more cause-neutral?

Spontaneously I find "Broad Rationality" a plausible candidate (I spontaneously found it being used as a very specific concept mainly by Elster 1983, but I find on google only 46 hits on '"broad rationality" elster ', though there are of course more hits more generally on the word combination)

I typically refer to this as "EA+", and people seem to understand what I mean.
