No. You are free to release your derived work under the terms of the GPL, but
that is not sufficient for the code to be accepted into the FSF repository.

And that's fine. But to respond to Manu in comment 11 and comment 13, we need
more than just a review, since the proof of concept attached here cannot be
used without the usual legal prerequisites being met. Another option would be
for someone else to provide a flat implementation, but again that is more than
just a review.
