EA isn’t (supposed to be) dogmatic, and hence doesn’t have clearly defined values.
I think this is a big reason why people have chosen to focus on behavior and community involvement.
Community involvement is just instrumental to the goals of EA movement building. I think the outcomes we want to measure are things like career and donations. We also want to measure things that are instrumental to this, but I think we should keep those separated.
