Provably false. Even a well-designed interface, if it is asked to deal
with a changing implementation and changing requirements, will
eventually either acquire cruft, or be found too rigid to be of use.
The only interface immune to this is the transparent interface
(effectively: "just package up the parameters in a single string and
pass it through"), which isn't really an interface at all, it just
exposes something else. In everything else, cruft is a reality that
must be dealt with.
