There was a problem hiding this comment.
Makes sense to me. &mut Components should definitely never be exposed to users. I do wonder if it's even worth exposing any_queued_mut and num_queued_mut as they seem pretty niche and are just faster versions of any_queued and num_queued. Feels like it's not worth complicating the api of ComponentsRegistrator for that. But I don't see any problems arising from exposing them. So not a big deal.
