Anybody know if this is a super bad thing to do? https://github.com/tweedegolf/sequential-storage/pull/19#discussion_r1450596765

Basically, I want `StateQuery` to be private, but the user needs to be able to pass a type that implements it to certain functions generically.
It is linted against, hence the allow, but from what I read from it it's mostly because it's seen as confusing? It's a warning too, not an error...
