Your incantation of the logical fallacy is how it often appears in what could best be described as ignorant conversations. The appeal to authority fallacy is if I measured the acidity in a lake over a long term period, and then presented my findings and someone declares that such can't be the case because the Environment Agency says it's fine. They're undermining my objective, demonstrated efforts with a hand waving appeal to someone else. If, on the other hand, I casually and lazily said "I think that there lake is acidic, no matter what anyone tells me", it isn't an appeal to authority to point out what someone who is undoubtedly in a better position thinks and actually knows. In this case someone offhandedly, based upon nothing but the fact that they seem to want it to be true, declared the ease with which the Go team -- you know, the actual people working on it -- could add generics. No fuss, no muss. It isn't an appeal to authority to point out that they are in absolutely no position to make such a claim.
