I think now, in 2010s most of internet content is made by regular users, not webdevs. Can we look at the problem from their perspective? Of course, CDNs and webdevs care about MIME types and Accept headers, but regular users know nothing about that and they've been happily posting apngs to Tumblr and DeviantArt for years now:

Judging by the comments, viewers seems to figure it out quickly. So what would happen if APNG support lands into Chrome "as is" and only IE/Edge is left out? These artistic types would keep posting that stuff, only a bit more often. What about CDNs and webdevs of big websites? Maybe a few of them would UA-sniff IE/Edge, but most won't bother they'll keep using GIFs. A few might switch to APNG exclusively, but that's hard to predict. I think the net effect would be slightly positive. And if Edge devs would follow soon enough, the whole thing could be moot, quickly. Three-way negotiations seems harder to achieve than convincing just one more player. Max. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
