It makes sense to extract this bit of the full rotation algorithm into a separate function, but it's unsafe to call unless very specific requirements are met that are unlikely outside the expected context. Being able to specify a local access level for the unguarded rotation would make this safer.
I'm curious if you could make the example more concrete and provide actual code that would benefit? One of the tough things about evaluating both SE-0025 and SE-0026 is that the proposals themselves contain very basic examples that don't sell the concepts.
