Yes, but without saying what the nodes exactly do.

I don't see them in the spec.

Even simple thing like DelayNode doesn't say in which way 
"implementation must make the transition smoothly".
And if implementations don't provide the exactly the same
output, using the API in music production would be pretty unreliable.
One couldn't play the same audio data the same way in different
browser.
