I don't really recall, but I probably used the same skeleton yeah.

Does it?

They're both pretty different actually. One is a gate + mux + reset
(patch 3), the other one is actually a combination of two clocks, one
that is the parent of the other, the former being a gate + mux, the
latter a gate + div.

At least at the hardware level, they're very different, and adding
more code to deal with both case would complicate quite a lot the
probe code, for no real reasons.
