        that simply using end-of-task could expose low-level implementation

        single task
        before the parser yields).

        Does Firefox do anything special here? Or does it simply use the same 
end-of-task delivery as everywhere else?

    end-of-microtask or end-of-task everywhere. And yes, some parsing / 
networking details may unfortunately be exposed, but in a way which should be
    quite random. Web devs just can't really rely on network packages to be 
delivered to parser in some exact way.

That randomness seems undesirable. Can we delay the delivery until 
DOMContentLoaded is fired so that we can have more consisnte behavior here?

Well, the randomness is about the same randomness which is exposed to web pages 
  <img src="http://www.example.org/nonexisting.png"; 

the order of 'img' and 'script' in the console is random.
