Earlier quoted context omitted.
What would it take to make a footprint database you can trust? I would imagine that community ranking/flagging of content could surely clean up inconsistent or invalid designs making the database more reliable. Would approved manufacturer accounts that contained all the parts from a manufacturer make them more trustworthy?
To your second paragraph, 100% yes :)
There's certainly a chicken and the egg problem happening with this kind of innovation right now. I know for a fact that there are many people at the large manufacturers that know that symbol and footprint library management is a major headache. They all want a good solution to the problem, but nobody is willing to take the plunge on an as yet unproven system.
