How do we make sure this is the case and it will remain the case in the
future? There must be some automagic to enforce/check that. It is simply
not manageable to do it every now and then because then 3) will simply
be never safe.

Have you considered coccinele or some other scripted way to do the
transition? I have no idea how to deal with future changes that would
break the balance though.
