Perhaps I don't understand the font features in question well enough,
but wouldn't a property such as

 font-variant: styleset(5, 13);

be totally specific to a single font file (what do the "5" and "13" mean
in general)? As such, I believe it should live only inside the
@font-face because it never makes any sense unless applied specifically
against the given WOFF file (in this example).

If this understanding is correct, then I suggest that the only supported
method for font alternates is using the @font-face directly as in the
example above.
