Comment 10 for bug 1658469

Yes, after discussing with others, this (nghttp2) will need to be reviewed for MIR (bug # 1687454) but has been uploaded for Artful.

It will probably not be backported to 16.04 or other releases without further review (as the version declaring HTTP/2 stability is 2.4.26 which is not the version in 16.04, etc.)
