That's correct.  We are currently working towards a v4.12 release in
Linus' tree, the upcoming merge window will be for v4.13, and things
merged into selinux/next after that merge window will be for v4.14.

While custom policies are definitely in the minority, we still need to
do out best not to break them without warning.

You very well may be right, I just felt that such a change requires
more than a week in the selinux/next tree.

Thank you for your patch, it's in the queue and I'll be merging it
into the selinux/next branch in a few weeks.
