Considering that the new feature only seems to be activated when the necessary hwcap flag is set, it seems fine for me to backport it. The one concern I have, however, is that 5 weeks is a bit long for us to wait. Typically, what I would expect is for us to cut the branch, then take a two/three weeks for people to field-test and stabilize, before we actually create the release. I don't have a problem with delaying the release after the branch get created, but 5 weeks takes us roughly to start of 2018. I would add an extra week or two after your backport before we actually release, just in case there are unexpected complications with the patch. So, we're talking mid-January. Any objections to a release around that time? -- Joel
