If I may rephrase the point:
A mandatory option 'that permits X' does imply, in my understanding, that you don't get X by default.
It doesn't suggest (as it should in view of the expressed consensus) that the default behavior MAY be X (then with an option "that deactivates X").

In the interests of heading off yet another repeat of this editorial discussion with Rémi and the group immediately after I post the draft, I'd like to get out in front and ask the working group if anyone else finds the existing language to be insufficiently specific on this point.

And more wordiness.  Don't forget the wordiness, not to be confused with verbosity.  Wordiness.  Mmmm, crunchy crunchy words.

This, I agree, is a more concise and therefore a better way to cover my point.
Thanks.

However, if there is a great hue and cry in the group for me to make this change now, and no major objections to it, then I may as well do it.  What's the groupthink on this?
