Ok, please point me to the *explicit* document in our tree which says: "we
won't break the kernel and support kexec with any kernel version"?

Something ala Documentation/process/stable-api-nonsense.rst

Which says things like:

"Assuming that we had a stable kernel source interface for the kernel,
a binary interface would naturally happen too, right?  Wrong."

Which I read as a "no" to the kexec question too.

IOW, it is not about whether it works or not - it is about enforcing that.
