Why are you still using GIF for this, when the PNG spec allows for animation? It's because it's not supported properly. Even after many years. Why isn't it supported properly? Because no one uses it. Why? ... Aaaand there we go with the chicken and egg again.

Again, AFAIK, we are not dead set on any one solution. Please lets keep an open mind about all possible alternatives and try to work towards meeting the requirements.

Yes, that is certainly on the cards.

Won't that cost problem go away once it's a common option? I do not want us to throw out a good, powerful, solution just because there are current problems for a small (yes, small) use case (i.e., site's that run at huge scale). The majority of sites on the web aren't Adobe.com (http://Adobe.com). 

Maybe, but we can learn a lot from TypeKit, which started small. If in TypeKit's experience it does not scale, then it should be noted that this may be an issue. As David pointed out, Google overcame this problem by "being Google" (i.e., they have a lot of infrastructure and computing power to throw at the problem). If another smaller entity solved the problem somehow, then it would be good to hear about it.
