Hi everyone! It is always interesting to see something that you have helped work on make it into the wild and see how creative people are that really want something! I will say that it is definitely not as easy as simply enabling things for managed users. As has been noted in this thread already, that scenario has caused trouble in the past. Managed users are a tough group for us as there are many different use cases for them. There are quite a few of those use cases called out here. Things like content filtering for family and children, as easy access users with the main account being more of a management config account, and a few others. We are actively in conversation internally as to how this could be done safely for the use cases that exist here.
The short answer here is that it is under consideration, and we need to make sure that we account for the different use cases and variables before final decisions are made. In the interim, stay tuned for some additional features that may help in a few of the use cases sometime earlier next year!
