Create a set of sharing profiles (admin not user level functionality) that allows partial delegation / sharing of an account. Ideally allow read + submit form on a per silo basis. Example use cases:-
1) Planning - share my planning information with my councillor;
2) Support for vulnerable people - share benefits forms with a not for profit that can help me claim.
3) Health and wellness - share my active lifestyles / exercise referral programme with my wellness support worker
