Correct. That is the ultimate defense with Open Source.

Breaking an API is extremely poor style and annoying as hell to everybody.
We all agree on that -- and what Romain proposed (ie removing unused cruft)
is generally a good rather than thing. But one has to be extra careful to not
accidentally create the former too.

The burden only grows with the number of users, and some users do have long
and slow upgrade cycles.  Ie we just learned about a commercial entities
being forced to use R 2.12.0. They are of course safe from all that because
they been excluded from any modern Rcpp for years already :)
