Of course it was. We could definitely have RcppEigen header only even 
with CRAN not header only Rcpp.

Those are two orthogonal things.

Releasing a new version of packages that depend on Rcpp after the header 
only version is released is a cheap and good way to deal with 
compatibility issues, e.g. deal with RcppEigen expecting libRcpp.
