Can you post a small example scene (eg a camera and mesh2 with just 2
triangles) that shows the gap where there should be no gap?

Ok, I can't resist it anylonger. The word you are looking for is "Hi!"
That word you keep using has a completely different meaning.

He's from the Netherlands and I think he means High! :-P

No, my English is good enough that I'm aware of that - "High!" long ago
became my trademark greeting to indicate my permanent POV-Ray-induced
intoxication! POV-Ray really turns me on!!!
See you in Khyberspace!

A very interesting use case (to me) would be e.g. to model a comet where a rough
3D model is available in the form of vertices (e.g. 67P from Rosetta data), and
you would want to add some fake detail in order to make close-up renderings look
less artificial.
If the mesh was an isosurface in the first place, modifying it to add additional
fake detail would be straightforward!
