Yes, this is clearly a substantive change that requires a WG decision
(and I'll want test materials in hand or at least actioned
when I put the question).

And there's a question of whether it's sufficiently large that we
should let the community review it again; i.e. whether we should
do another last call.

We can either make our own decision to do another last call,
or we can propose that we don't need one, but The Director
could say "yes, you do."

I haven't made up my mind what's best.
