[Gmsh] Conformal mesh on two parts

Why does the faces have to be connected by an geometry option in GMSH?  
We could GMSH just tell the faces are connected, or give GMSH the  
geometry with connected faces allready, couldn't we? Would this allow  
GMSH to make an conformal mesh on curved faces?

The question would be how could this be done. May be by directly  
passing a BREP in which the faces are connected allready? Or by the  
use of geo format?

Mhh, most important would be if conformal meshing on curved inner  
faces would be possible by GMSH if passing appropriate geometry to
