Sure, but bigger and smaller scale operations have different needs. The internet isn't supposed to be about what's best for the big guys, it's supposed to be about what's best for humanity.
The "specifics" in the other threads are more ad hominem. You're saying "we should be wary of what Google does" without actually mentioning what's there in the spec to be wary about. You're saying "we shouldn't trust Google to pass specs unchecked", people are saying "but we aren't: we've read the spec, and it's good", and you're saying "yeah, but we shouldn't trust Google".
Sure, the general trend is a good point, just not entirely relevant to this specific thread. Your comment above does make good points about the actual spec, I agree.
I've mentioned specifics elsewhere in this thread, for example, https://news.ycombinator.com/item?id=6013468 and https://news.ycombinator.com/item?id=6012906
