I think it’s a cool feature, but playing devil’s advocate, this new ability also means that users will be able to make a lens perform worse. That wouldn’t be good marketing. It also has the potential to send the message that, “Our products are sloppily constructed and have been widely reported to have serious calibration issues, so we’ve decided to pass that stage of our manufacturing/QC process on to you, the consumer.”
I can see the complaints already, “I’ve tried adjusting every setting and my lens won’t focus at all. Don’t buy Sigma.” Imagine if car manufacturers gave us the ability to tweak the engine and transmission computers? That would be great for enthusiasts who know what they’re doing, but it stands to create more problems than it would solve. Add to that a tendency (that’s tendency) for Sigma buyers to be less-experienced photographers who may have greater problems with their technique than the performance of their equipment (which would be me).
Not evey lens can be perfectly calibrated to each body, Canon, Nikon, Sony, Pentax. This software is meant to adjust for those small variations. This is no different than in camera Micro adjustment. The only difference it is the lens being adjusted. Each time a manufacture comes out with a new body there is a chance a third party lens wont work. This software can help update the lens so that it will.

The "hide" button works especially well in this regard.
