I would be most curious on *how* we would go ahead and actually deprecate User-Agent for real on the web. Just saying it in a document like that won't be enough. I'm sure that removing that header in requests will break the experience on N% of the world's web sites, which I doubt browsers would like to impose on their users. I expect that nobody will remove this header until such an action is likely to only cause an insignificant amount of user pain, and the same time the world's web sites with all their user-agent sniffing logic are unlikely to actually swich to CH as long as the vast majority of the browsers keep sending User-Agent headers... The good old depcrecating things on the web dilemma. Or are there reasons to believe this time will be different? -- / daniel.haxx.se
