Easy. The bufferedAmount is: "The amount of bytes waiting to be

That doesn't define exactly what the bufferedAmount means and what
kinds of values are expected.
What I'd expect the API to tell me is, for example, that if I call
ws.send(foo), and nothing is yet sent over the network, what is the
exact value of bufferedAmount.
Again, I'd really wish to keep the API to work reasonable similar
way as XHR+progress events where protocol overhead isn't reported.

Why? Progress events are completely different from this. This is about
not saturating the network with too much data; it makes sense if the
actual amount of data that is going to hit the network is known.

bufferedAmount is not only about "not saturating".

Let's put the question otherway around:
from API point of view, why should bufferedAmount contain some bytes
which aren't specified in the API spec?
If the API specifies that bufferedAmount is always to_be_sent_data_in_UTF8_length+(1 or 2), that would be sort of ok.
Very very ugly, but ok.

Also, some implementations may not put the protocol
overhead bytes to the buffer at all, but just write them to the
socket when needed.
