From your test case I think we should not provide a default rule name. Otherwise it's easy to get the rule name conflict if users call PreloadCustomSketchRule twice.

I'm still not clear about the registration mechanism with the decorator. I agree with you that using the preload callback should be sufficient for users to specify custom rules, and it seems just a fast path without any additional functions that the preload callback doesn't have. Accordingly, should we just remove the decorator and registry to make the design simple and easy to maintain?

I agree, decorator has been removed.
