Hi,
(Forwarding this on on behalf of a fontspec user who would like a new feature. Not currently subscribed so please CC me directly if you have further comment.)
TL;DR: +lfbd feature works in XeTeX but +rtbd does not.
If there are further requests for fontspec OpenType feature support, please let me know via Github :)
All the best,
Will

Will, sorry because I was so stupid not to recognize what I already knew.

What I knew: opbd is handled by the application, not by the font (which provides both lfbd and rtbd, but no opbd).
To test both sides of optical margin, I added rtbd values to the font provided for testing at http://www.ousia.tk/TestOPBD-Regular.otf <http://www.ousia.tk/TestOPBD-Regular.otf>.
The partial failure in XeTeX is that rtbd doesnât seem to work.
Iâm not subscribed to the XeTeX mailing list. If you were, would you be so kind to report this issue there?
I guess an option name such as OpticalBounds or OpticalMargins might make sense here.
