Apologies for the massively tedious review. I split it into lots of commits so that each commit (except the last few) does exactly one change. And I already have conflicts since I started this last night, lol.

I wonder if this should be create_diag_ctxt or something

I don't see why function names need to be different to variable names. Consistency is good.

It's consistent with variable names, but not the type name. I consider it more normal for a constructor function to be called create_type_name, personally.
