I disagree that your comment does not add any additional constraints.
One could argue that there is enough ambiguity in the GPL and Linus's
explanations regarding uses/derived from, to allow proprietary modules
in the current module framework. Others can argue the other way. (Refer
back to Crispin's latest email.) Your additional
comment fixes one of these points of view (call it a refinement rather than
a constraint if you will), so it does go further than the
original license did. I think the comments we've seen proposed from Crispin
and jmjones (sorry if I attributed the sources incorrectly) are alright, in
that they discuss what is encouraged and discouraged, but do nothing to
refine the original GPL. If such "style" language is not appropriate
for kernel code, I have no problem in leaving it out either.

You believe your comment does not place any new constraints on the license.
I do believe that it does (because the GPL leaves room for interpretation,
as Crispin has noted). Would it not be safe, then, to just leave it out
entirely? You still have the same licensing (that is, no new constraints),
and the few of us that believe otherwise are mollified.
