You can look at chrome&#x27;s behaviour for the last couple of years to get an idea of how this might play out.  Basically, the big browser vendors <i>are</i> the new standards bodies, and the w3c&#x2F;whatwg plays catch up with what the browsers are implementing.  If three browsers all agree to implement something, it gets implemented without waiting to hear what a standards organization says, and then it gets documented in a standard later on.
