The definitions are currently very clear.  What you have described
differs from the current definitions and therefore would not be a
clarification to the use of admin class but a change in semantics.

I do not know of anyone using more than a handful of admin class bits
and many who do not use them at all.  Lets not take any MPLS
capability and make it any more complicated than it needs to be or
introduce arbitrary change for no good reason.
