But maybe it should be defined in a somewhat more abstract terms than
directly in terms
of the XFree86-specific vidmode extension terminology. Ie offer to change
the refresh rate,
not some cryptic NVSCAN or DBLSCAN parameters which (at least I) don't
understand at all.

It is, but it has a scope, which is explained in the introduction. Certain
aspects of wm-client
interaction are explicitly declared as out of scope for the EWMH. The
question I have is whether
this vidmode changing is too specific for the EWMH, since only very few
clients need it.

If there is no interaction, than this should be explained. The paragraph you
just wrote may be
a good start for this explanation.
