What are you trying to do that you can't?
The permissions granularity for something being readable is to low. For example, it should be possible to allow particular people to see an org, a process, etc., but instead, it's only public, everyone in an org, or admins.
What is your idea?
There is already an "authorized" list on most tables with a visibility setting. Build the front end for that and account for it in row level security.
