I am rather asking if there is any possibility that package review request (BZ1332306) stalled for ages would get some care. Had I been a packager, sure I would try to handle the review process myself, but I am not a packager. It would be nice to have some contributor giving the libc++abi package some time, I am quite sure there are many people who will be very grateful.

packagers packages proposed for inclusion into Fedora.
