Would slowing Julia's release cadence improve ecosystem quality?

I don’t think so. And I would want to go the other way, have more frequent releases.

I don’t see much of an ecosystem quality problem, relating to new Julia versions (I think others agree here, except for a minor update problem, and I proposed how to fix that):

I obviously don’t control the frequency of releases, but if each one is trying to be a smaller upgrade (maybe not trying to be very small) then they can be more frequent, and less of a worry to miss the feature freeze. People might argue it’s too much work, but we have up to 6 point releases, and with more 1.x releases, I think we need fewer if any 1.x.y, so less backporting work.

[Julia is the first language I’m involved with contributing to. I’m not sure, does Julia have more regressions than others? I have no way to back that up, could actually be fewer. Do people think too many/more than expected? And I’m thinking of genuine ones, fixes (or needing) in point releases, not talking about stuff an upgrade of packages fixes.]
