Most apps create subset font names by prepending six majuscule ASCII
letters and a plus sign to the original font name, following Adobe's
recomendation in the PDF reference.  I'm sure Illustrator expects that
and would Do The Right Thing were cairo to also use that style.

The norm is either a random string or some relevant digest (perhaps of
the font's version and the list of glyphs included in the subset).

There are workflows where avoiding subsetting is required, so a flag for
that is useful.  But it would also be useful to use the normal method of
naming font subsets.
