In a marketing
context, I would not speak of a “variable font”—but of a “variable font family”.
As a technical description, or as a name of a format, “variable font” makes
sense: it is (like) a single font that can vary. As a functional or marketing description,
the term “variable font” (singular) may suggest to be less than what it is.
Functionally, a “variable font” is not one font—but a font family with a few,
many, or very many members. When selling variable fonts—using the label
“variable font”, would be underselling your product, in the sense of
suggesting that it is less useful than it is.
In a marketing
context, I would not use “non-continuous” instead of “discrete”. “Non-continuous”
is an accurate technical description—but labeling something you sell as “something
which it is not”, does not seem to be a good marketing approach.
Whatever labels will
be used for variable fonts in a marketing campaign to introduce them—prospective
customers should, in that campaign, always get very clear answers to questions
like “What are they?”, “Why would I want
them?”, “How do I use them?”, etc. So, whatever terms or labels will be used
for variable fonts—there will always be a job of customer education. And
indeed, when there would be “two types of variable font families”, prospective
customers should also be educated about this.

Well then, perhaps OTVF ?
The recommended file name extensions remain .ttf and .otf
It's an extension of the OpenType format, folks, not a new format.
Because OpenType Font Variations is a new technology, it requires substantial updates to font handling infrastructure in operating systems and/or applications, and has very limited backwards compatibility; this also differs between the TrueType and CFF flavours.
It is anticipated that some font customers will, for some time, need both variable and non-variable versions of fonts, for deployment in newer and older environments.
In addition—it might
be a good idea to have a metadata entry which identifies a variable font as
either a continuous variable font, or a discrete variable font.
In the case of variable fonts, the presence of the 'fvar' table is the most reliable indicator, since this is obligatory in both TTF and CFF variable fonts.
