Would it be worthwhile to warn about unmentioned typed $$ as well?

The correct handling of $$ is troublesome when there are midrule
actions.  I tried to see how this could be implemented peacefully
in bison, but I gave up: there's a lot of code duplication here,
complexified by games played with "current_rule" and "previous_rule".
This is the kind of things I'd like to get rid of by moving the
translation of $$ etc. in a second pass, in a second scanner.

So I propose that we leave it as is for now, later, with a cleaner
set up, it will be easier to have it right.

I installed the following.  Note that the warning is somewhat annoying
with rules running YYERROR etc.
