Is there any guarantee it will be like this? I don't think so. That's
why there is an IWYU principle to give more flexibility of reshuffling
the (core) headers. And I believe you know that we have way too far
dependency hell in the headers in the kernel. Have you seen what Ingo
tried to do and what the potential achievements are?

(this should be "non-probe deferred functions")

Yeah, I got it, some developers are leaving in the previous decades to
make code very verbose for no benefit, no problem.
