I would imagine that few who use an S900, either philosophically or budgetary, have got the slightest interest in a V-Piano no matter WHAT it did!
They don't even do the same job. No OMB is going to use one of these. A top line pianist, yes. A studio pro, yes. A home pianist with the money but not enough room for a concert grand, yes. But an OMB or 'home' player (read amateur 'plonker'

) doesn't have the slightest need for this.
That doesn't mean there is NO need for it at all, just no need for an OMB...
It isn't ALWAYS just about you, Ian!
