Well, it would also be nice if it had more than one input. It would be a bitch to replug it everytime we need to switch sources. Part of the reason I'm typing this post on a 40" Bravia TV instead of a regular desktop monitor is that it has an optical output (which actually outputs a Dolby Digital Signal, not some downscaled absurdity). I can switch the X7 between my PS3 and my PS4 (And X1) in the future by simply switching the channel on the TV.
Those are details. The important part is getting them on board with the idea of even making on in the first place. Baby steps.
At the end of the day, if Schiit made something that only took optical in and output virtual surround to a headphone jack using the Modi and Magni tech (think Magni+Modi+DTSHX in one box), it would still crush pretty much any other option on the market. The X7 would compete solely on its flexibility.
