Why isn't hasura.user run-time parameter set on queries?

I know that Hasura is a little opinionated with regard to row-level security, and where it should take place, app level vs db level, but I'm feeling a bit hamstrung at the moment, because I have my own opinions, and would like to enable RLS for select statements on the tables backing my Hasura deployment, but I don't have anything to work with, since the hasura.user run-time parameter is only being set for mutations. Other API solutions like PostgREST set run-time parameters for everything, so I'd like it if Hasura would at least make transactional queries w/ session data run-time parameter included a configurable option, perhaps in the SelectPermission definition.
