I think 3.5% of pageloads (from chromestatus' metric 1054) is a bit more than "millions". > The fact that we're only getting the interoperability issues discovered > as we roll out the feature to stable is sad; I don't know how to get > other people's software tested earlier in the cycle, which is what would > have given us more time to work through these issues. Have you tried talking to said other people? (this is rhetorical. I remember the dtls 1.0 deprecation and many other cases) in this particular case I reported that the previous choice of putting an empty string into c= was broken back in January: https://bugs.chromium.org/p/chromium/issues/detail?id=927309 I find it quite sad that this was fixed without verifying that Firefox (which I indicated as 'throws' in the second comment) is ok with this. (yes, I could have tested this myself; OTOH this isn't part of my job) I suspect the interop issue with Firefox is restriced to non-trickle usage where no stun/turn servers are used. Which might be uncommon in general (for P2P) but might be a highly relevant deployment scenario for some applications that talk to servers. This is a pattern that has broken things in the past (see for example the "unified plan breaks my cma" episode) because errors in those apps are not visible in the very noisy system that "chrome as a whole" represents.
