Yes, that would be very nice.  But I think introducing something like
that would be difficult...

Introduce a new syntax like

;; Local Variables:
;; foo-bar: t boundp
;; End:

is difficult to make backwards-compatible, but perhaps we can come up
with something that older Emacsen will ignore but newer ones can parse?

We could also introduce a new section for these variables:

;; Boundp Local Variables:
;; foo-bar: t
;; End:

But...  I'm not much fan of that.
