J3 should at least have a cursory look at it, maybe only Clause 2:
Requirements, to decide whether to advocate for it, as a national body,
at Delft.  This could wait until February.  Maybe if we ponder it
offline via email, we could vote yea or nay at a February TAG meeting
without taking much plenary time on it.  On the other hand, there are so
far no papers for 199 in the repository.

I don't know about the "superior" part, but it is certainly simpler.
Also keep in mind that we could still do macros or parameterized modules
later, without changing anything in the specification of parameterized
subprograms, as described in the paper I circulated yesterday.

Speaking of that paper... I've moved the specification of the default
value for a subprogram parameter from the subroutine or function
statement to an INTEGER, KIND statement, for consistency with type
definitions.  If and when the paper appears at a meeting, that revision
will be in it.
