I think you're wrong. Those are these users which ask for feature XXX or YYY that they like because it brings them a better experience. If you can find a real benefit for the end user, there will be an option in the browser and some of them will enable it. It's just important to find how an end user may benefit from making use of SRV tags when connecting to his favorite site instead of using just CNAME or A/AAAA. Maybe being able to always connect to less loaded servers would be appreciated, because some site maintainers will start announcing new servers. Maybe there are solutions to provide better geolocation using SRV than with A (ie: let the web browser decide which field to use instead of relying on its resolver's IP address). Maybe it will be possible for mobile users to automatically select a different port which is not subject to annoying transparent proxies at their provider. I don't know. You must think in terms of better experience which might be brought via better quality of service. Surely a DNS record might provide information to improve QoS based on the browser's decision. > So we are talking about webbrowser vendors, right? and typically there > are no more than.... 10? Browsers implement what their users ask for. They don't want to add features that are not desired and make experience worse or reduce reliability. But if users ask for something, they'll certainly implement it.
