I was wondering if it would make more sense to supply the error directly to the function instead of the boolean, but there is only one kind of error and I also don't really see a usecase for that. So I think this is fine the way it is.

Agreed! It seems to me that the amount of work of adding a boolean and an error is similar, and the latter gives us more flexibility going forward, so I'd recommend doing it now.
