IMHO, these considerations don't matter when a NEWS entry is being
considered.  What matters then is that something which didn't work
before works now.

I won't start a dispute out of a 5-liner, so go ahead and commit your
version.  However, at the very least replace "commercial" with
"proprietary".  This is a distinction the FSF asks us to make (there's
nothing to prevent a free software project from going commercial as
long at is stays GPL-compliant).
