It is based on v9_11 and contains a step-by-step account of the backporting process. All changes in rt46430 should be applied to v9_11, while v9_10 and v9_9 will only need the fix for RT #46055 (one-line change to lib/dns/zone.c) as the mkeys system test did not exist until 9.11. I put the updated mkeys test from the v9_11 branch on a spin for two hours on Fedora 25, FreeBSD 11.0 and OpenBSD 6.1 VMs and no issues were exposed, so I expect the branch to be at least relatively stable.
