If that is true, then shouldn't we have an implementation of row level
security *first*, and then an implementation of selinux hooks that
work with this row level security feature? Rather than first doing
selinux hooks, then row level security, which will likely need new
and/or changed hooks...

I'm not convinced that row level security is actually that necessary
(though it's a nice feature, with or without selinux), but if it is,
it seems we are approaching the problem from the wrong direction.
