Nothing has been explicitly done to prevent it.

The "feature" is a warning which you can interpret as "It might or might
not work in your scenario. Before you rely on backporting projects in
production scenarios, test it carefully.".
Or test one version and stick to that within a project which is the
safest choice.

Changing this behavior would be a considerable additional amount of work
and slow down development of new features (and there would still be no
guarantee).
