And what's stopping them to put DEFAULT_PREFERENCE_machine and
COMPATIBLE_MACHINE in the kernel recipes?
There is no technical reason for setting it in machine.conf, so why
should we break the orthogonality for that?

That is actually an option these days since most kernel recipes set
COMPATIBLE_MACHINE correctly :)
But seriously, there are use cases for one distro to use a different
kernel for a given machine for whatever reasons.

This whole situation is a mess because recipes/linux is a mess. It would
be a nice topic for OEDEM to see if we should switch to a poky BSP
model. It would boils down to:

1 bblayer per machine or SOC_FAMILY containing:
* machine.conf
* first and second stage bootloaders
* kernel

I can see some serious issues with that, but that's for another thread
to discuss.
