That would be a new thing as these variants don't exist yet, and WITH
is for storage parameters.  In my opinion, the long-term take on doing
such things is that we are then able to reduce the number of reserved
keywords in the grammar.  Even if for the case of CONCURRENTLY we may
see humans on Mars before this actually happens, this does not mean
that we should not do it moving forward for other keywords in the
grammar.
