I get the impression that development has realized with v12 that they have spent too much resources on developing new features and not enough on reliability. Personally I would rather have a Chevy on the road than a Porsche in the garage. Their crediability is not going to be built on having alot of features that constantly have issues but on relibility of those features. For serious site developers they will frustrate them to the point of just throughing up their hands and calling it quits. I have often consider doing that myself after spending almost as much time trying to get something to work or waiting for the fix as developing the site. I think UNA has great potential and may in the next 10 years or so become a professional site builder platform. Right now if you want a simple site it works fine.
