The trick here I think is consistency - is name-generated type dispatch the standard across the entirety of the codebase? If it is, go wild. If it's not then I'd be much more wary of it.

Consistency and building correct expectations for future maintainers is pretty important. Doing a smart trick in one place but failing to do it in other places where it makes sense IMO tends to create a bigger mess than doing it the dumb-but-safe way everywhere.
