I rather have this fixed (or clarified) in RC 7950, as far as I
understand I can choose to ignore the versioning extensions and
simply use YANG 1.1, no?

That said, draft-ietf-netmod-yang-module-versioning-02.txt says
in 3.1.2.:

   o  Modifying the type of a leaf or leaf-list is NBC

This seems to be way more restrictive than the existing YANG 1.1 rules
we have today. Perhaps that is what the versioning people want, but
then we better keep the YANG 1.1 rules and the YANG + versioning rules
separate.
