I would rather neither requires writing custom triggers but rather both
are supported through this feature.

This I don't agree with- the plan has long been to have PG-specific RLS
first and then to support SELinux capabilities on top of it. We didn't
want to have SELinux-specific functionality that couldn't be achieved
without SELinux being involved, and I continue to agree with that.
There are many situations, environments, and individuals that would
view having to implement RLS through views and triggers as being
far-and-away too painful and error-prone to rely on.
