I agree. It was a perfectly legit use of ::: but then the powers of CRAN do
other things do we don't agree with but cannot easily alter.

That's pretty.  For all the Rcpp-using package, we can assume Rcpp to be
there so it may as well pivot over and call a plugin from 'foo'.

| Sure.

The other immediate defensive way would be to use NAMESPACE etc on the client
package and not load Rcpp and Rcpp$foo but just importFrom() etc what is needed.
