The "wrapper" storages we have now with FlaggedStorage and ChangedStorage aren't very flexible. Since I'm sure someone down the line will want to check for changes for some component that doesn't have the wrapper storage. (Since I've run into this plenty of times already when trying to implement UI stuff with specs to the point of where I just add the FlaggedStorage for all the UI components so I don't have to worry about it anymore.)

We might be able to add some Vec<Box<AddonTrait>> and abstract away the "real" storage (DenseVecStorage, HashMapStorage, etc.) so they can't be modified except through some interface.

Coming back to this I have something working and actually kind of nice: https://gist.github.com/Aceeri/39b23eb18bf05848ee44c21c5e34e14a

Should this be closed as the PR was rejected in favor or Tracked?.

I think so.
