Consolidation in this context means closing one community and redirecting people to another to make one more active. The fediverse is small, and so having niche® communities combine into one is often beneficial for them.

Don’t know if you are a regular in this community, but such proposals are pretty common (and I will take the liberty of saying cm000, the main poster in the other comm, is even open to such approaches).

Even if we did have say 1 million MAUs, it still makes sense to have some sort of differentiation between communities (rules, regional focus, types of games etc.); currently there is none.
