I have a hard time seeing anyone actually use this for one reason: it's not Illustrator. Build something that allows them to completely use their existing, frankly much more user-friendly, workflow with no changes and it might at least get looked at. (Illustrator already supports EPS, but since everyone who matters already has Illustrator, not a lot of people bother, even when not running outside EPS's format restrictions.)

Nobody cares about your standards if meeting your standards doesn't benefit them. And the people actually creating stuff own Illustrator already.
