Merely that we want CC BY and BY-SA 4.0 to be considered free licenses
under that definition.

Of course. I was only pointing out, perhaps too obliquely, that, as
above, we want CC BY and BY-SA 4.0 to be considered free licenses per
freedomdefined.org, and any proposed change should be vetted against
that. As an example, IF a strong proposal were to come forth for
adding a requirement to use free file formats (such a proposal would
not be coming from me; though I strongly favor free formats, I highly
doubt the CC licenses are the optimal place to mandate that), one of
the hoops it would have to pass through would be not making BY and
BY-SA nonfree, ie would have to be within a permissible (which is a
MAY, not even a SHOULD as far as freedomdefined.org is concerned with
license conditions) restriction.

Yep.
