I wonder if 25,000-ft is for quicker certification and they'll end up

their composite airframe life numbers

I read the lower ceiling was more an issue with RVSM. By certifying the
plane (I realize this hasn't happened yet) with a ceiling below
29,000ft RVSM equipment is not required (cost factor) and the pressure
hull doesn't need to be as stout to handle the higher cabin
differential (cost & weight factor).

Give me Spectrum's construction methods (link), with a single (mini) HondaJet engine, on a mini D-Jet single seat platform. I'm telling you there's a market out there for this!! (Not kidding)

I think an autogyro might make a better commuting vehicle. Much easier
to find a landing spot than a jet, and no type rating involved. But, a
single seat jet would be the ultimate toy for the gotta-have-it crowd.
