Or, an alternative is to specify the constraints in OPAM such that an older interface that hasn't changed would be included in the constraint, and hence not trigger an upgrade unless required.

Yeah they would.  I was thinking of a heuristic that would require only the root packages to be upgraded to their latest versions (that is, the ones explicitly installed by the OPAM user), and leave intermediate packages until a full upgrade is requested.

However, it would just be easier if the versioning was decoupled from the get-go.
