Above the code seems to assume that regmodel is a TableRegressionModel, so you could just do regmodel.model.rr.mu and remove _rr.

I'm a bit surprised that you need to add this, as usually method delegations were only done in StatsModels, for functions from StatsAPI. For example, below Distribution isn't defined for TableRegressionModel. Where is this method called from?

They're called in the tests.

Yeah but I wonder why we never needed this kind of definition before. I think the code was designed so that we never called functions on objects which could either be AbstractGLMs or TableRegressionModels.
Maybe this doesn't matter much as 1.x is a dead-end anyway.

This accessor isn't introduced by the PR, right? Why are tests added then?

They were part of the cherry-picked commit.

I don't see it at https://github.com/JuliaStats/GLM.jl/pull/507/files. I think this comes from the commit which removed TableRegressionModel, which isn't relevant here.
