Double wildcard paths like collection** on change events (missing return value)

I can't get hooks like `store.allow('change', 'collection**')` or `store.allow('change', 'collection.**')` to work, any validations added on such paths will never trigger. `store.allow('all', 'collection**')` still triggers fine, which I think has to do with `_allow_all` checking manually for those kind of paths. Are these patterns not available for change events? Is the missing return value a bug or was it intended? 

How can I capture all changes under a specific collection?
