Right. I agree it works. But the, it obliges you to modify the mesh each
time you visualize another result. I do not think it is the right way to
do it. If my mesh represents a structure, I do not want it to be changed
each time I visualize another result. In Nastran, "point elements" are
sometimes used ; for example, CONM2 elements (concentrated masses). But
these elements are not defined to visualize results.
I think the file format you propose in GMSH isperfectly correct. What is
missing is the possibility to visualize values "on a nodal basis". For
example, if a devine a scalar or vectorial value _on a single node_, I
would like to be able to view it with GMSH (as a colored sphere, or as
an arrox). I think that it is so far not possible, and I am sorry for that.

Ok, I see.
Something that works mostly like what you want is the "Element boundary
mode" option in the Visibility tab. It allows to draw one glyph per
vertex (if you select "Dimension-2" in 2D for example). However, since
we still draw "element by element", if you don't define values for all
the nodes in an element, this element will be skipped (as it is not
fully defined)...
