Can row level security policies also be implemented for views?

I'm developing an application where strict control of my data is important. Views allow me to build a strict custom reading experience, allowing me to add computed columns and hide private and metadata columns. Row level security allows me strict write control of my data. However, I can't use both technologies together, why?

It seems easy conceptually, RLS just adds a WHERE clause to queries if I'm not mistaken, and conceptually a view is just a query. The CURRENT_USER issue is valid, but personally it's not too big for me as most auth is done through database parameters.
