Good. UserAgent-based feature detection needs to be broken every few years as it is a gross abuse (Aggravation; like Rant) I'm blown away people see this and react with "if we had more of a singular monoculture, this wouldn't be an issue", when the exact opposite is true. Making it difficult/near impossible for newcomers/outliers to operate in the browser space is very unlikely to improve things in the long run. I'm sure Opera had many reason to cave in and throw away their rendering engine in favor of a webkit fork, but I suspect having to continuously swim upstream against the ever growing proprietary extensions and broken browser detection logics out there might have played a role. -webkit prefixes are supposed to stash away experimental features until they get standardized, but with the webkit monoculture, they become de facto standard as their implementation trickle through the webkit forks and releases. That's harmful. Perhaps having faster standard tracks where prefixed features don't have time to become second nature for webdevs, and fostering a culture of "proprietary prefixes don't belong in production code" could help here.
