This is the one reason I can see for cutting this extension in smaller
pieces. But, then again, -XOverloadedRecordUpdate would be a fork-like
extension.

Generally, I'm not in favour in proposals which split extensions though: we
already have so many extensions. Are the reasons for this split strong
enough? I haven't had time to dig into the details.

I'm not sure that not having the design of the proposal quite finalised is
a good reason, extensions mutate in their first iterations, I don't think
that it's a problem.
