Re: [K3d-development] SubdivideFaces fails to cope with letters such a "e" on PolyText but TriangulateFaces does a reasonable job.

MergeMesh creates the union of two meshes ... in your case there are 
still two separate polyhedra.  This would be a use-case for a different 
modifier (or a new option in ExtrudeFaces to create / retain the 
original back-faces).

What is the desired end-state?  I don't imagine that a 
convex-polygon-and-hole-aware SubdivideFaces would change the outcome of 
CatmullClark in a meaningful way.
