Olaf,

Indeed, extracting the code that has been made private in core 
and duplicating it in the package is a solution, but I really
wanted to avoid this.

Also, as far as I remember, there is no reliable way of exporting
C++ headers and libraries from one package so that others can 
use it, so if multiple packages use this functionality the code
must be duplicated multiple times.

I think having a public API to do this in core is the best solution,
even more so if the same code is in multiple packages.
