This is a programmatic API.  I appreciate the concern for a bloat of
bits on the wire, but recall that features are listed in yang-library,
a very special module that has a built-in ETag-like hashing mechanism
to allow for efficient comparisons.  I don't see the bloat issue here.

Having feature statements everywhere may be ridiculous, but not illegal.
Implementations need to be able to handle it already, right?
