something like that ...
keep in mind that you don't need to define a font then,
{\setfontfeature{smallcaps}Some Text}
will automatically give you that featureset so in practice we can do
with only a few real font definitions; mkiv keeps track of such dunamic
features and efficiently caches data;
we sped up luatex + mkiv some 30% and when using dynamic features with
huge fonts (zapfino, arab, chinese) we can even gain more
(our sample mk.tex went from 29 seconds down to some 20 seconds and
dynamic arab gives another 2 a 3 seconds; a fast console another 2+
seconds but that's another story; just in case you wondered why it took
a while for this beta to surface)
