Hi Daniel,
We are in beta for v18. I expect release in September.
I don't think we have to consider users who run older Kodi versions on
systems with latest kernels. The feature the patch would disable won't
make Kodi completely unusable when absent. I'd say you can merge
the patch short after v18 has been released.
Cheers,
Rainer
