We see several benefits with this format: It integrates with contour definitions from glyf and CFF2 tables and thus enables OpenType variations for a vector color font format for the first time.

You might be interested in this lightning talk I did for BlinkOn 13: https://www.youtube.com/watch?v=6Wgh5x7mLSM&t=50s The lightning talk is based on materials made together with Rod Sheeter and Cosimo Lupo and was originally held as a talk on the 44th Unicode conference.
