I have no plans to stay on a given release once the next is out at
this stage. My goal is to get all of the code upstream, so that I
don't need to maintain any out of tree patches, and then system
integrator can pick whichever kernel they want for their system.

It would be straight forward to maintain a stable tree once the "dev"
tree has moved on past 4.19. I have some ideas on how this could work
if you are interested.

I encourage you to get your patches on the list! Do you have a run
down of what you keep out of tree?

Cheers,

Joel
