I think he kind of had a good point. It would be nice to have a single set of tools that can always get the job done no matter what.
He gave me his version which was around 10x more code and only worked in a subset of the latest browsers, while mine not only did but would probably work in everything since maybe IE5 or so...
Maybe that's considered a bug, but I don't want any of this trend-chasing. I write code to get things done. My users don't care, and they want to get things done too.
The first step is knowing that the current state of things is deficient in some way.
