Also there seem to remain a few uncovered lines (apart from the @static if VERSION which is obviously a bug).

I'd generally be a lot more comfortable if there was some kind of reproducible way to get these reference values (even if it's in a script that doesn't actually get automatically executed during tests). but otherwise looks good

Can you copy the relevant parts from that file instead? It's weird to rely on MixedModelsExtras for that, especially if this PR is supposed to provide the same features more upstream.

I mean, the relevant parts of that file are just the reference values. I'm planning on writing out the R code to do it again, which is why I hadn't merged this PR yet.
