> One key example is this:  7950 says that adding another enum to an enumeration leaf is NBC (and that applies to state). But that may not really be how most implementations would want to treat state. Would we really want to flag a module as non backwards compatible when a state leaf gets an additional enum?  Wouldn't that create a lot of unnecessary noise?

I read this in RFC 7950:

   o  An "enumeration" type may have new enums added, provided the old
      enums's values do not change.  Note that inserting a new enum
      before an existing enum or reordering existing enums will result
      in new values for the existing enums, unless they have explicit
      values assigned to them.

What do you want this to change to?
