We need more feedback on this - Thomas, David? Should we include more people? The reason for this change is we want the build without any meson options (specified on cmdline) to be usable on as many different machines of the same architecture (this is my understanding form the discussion with Bruce), which is the generic platform. We could preserve the current behavior by setting the default to native, so we just need more discussion.

I don't understand why you need to change the behaviour.
If we change the behaviour, it must be done carefully
after a deprecation notice and an agreement of the Technical Board.
