That is the same with systems which only provide static linkage.
We cannot do anything against that; only, we shouldn't imply in
the documentation that the user can expect anything better either.

Aside, most systems where $major is not $current-$age will need
relinking after a compatible API update (case 2).  This is the
more relevant case I'm thinking of, I guess most users know about
the case of totally featureless versioning.
