I don't know if it's an enhancement or a bug.
Indeed, I found references about AAT (see http://opengrok.libreoffice.org/search?q=aat&project=core&defs=&refs=&path=&hist=)
There is like a signle AAT variable font publicly available (Apple’s Skia) and the technology is deprecated with the introduction of OpenType variable fonts (that we already have an issue open for it). So it makes no sense to even try to support AAT variable fonts.
