We are still in Stage 1, but I don't have many details at the moment, I would
suggest simply following the various announcements on the gcc mailing list.

Ok...

If you ask me, normally we don't open many PRs for pure enhancement issues, the
situation can quickly grow without control. After all, Bugzilla is for *bugs*.
Thus I would recommend summarizing those issues to a minimal number of PRs,
better if each has a student already "assigned", somehow.
