Well, removing kernel.h is essentially IWYU, as we have to include the actual
used headers we were pulling in transitively. It should definitely be a task
for newcomers, nevertheless as Jonathan says it's not exactly easy to do from
the get go (and automating it with iwyu-tool can also be a headache). Also,
I've had a pretty good experience with AI when it comes to verifying headers.

I'll probably send a series removing it from some sensor type subdirectory,
just to get the ball rolling?
