Well, if you want to call "well-defined interoperable error handling"
"guesswork", then sure. I guess that's just terminology.
The point is the browsers all do the same thing, and that's well-defined

Well, if all the browsers do Z, then since the author presumably checked
his page with at least one browser, and it did Z, and he didn't correct Y,
then the assumption that Z is what Y was supposed to be is IMHO a safe

This is somewhat out of scope of the WHATWG work. In my experience with
usability studies, unobtrusive, ignorable icons are a waste of time, and
in my experience with browser vendors, they mostly try to avoid UI that's
a waste of time. I doubt a mainstream browser would support this feature.
It's certainly possible, though, and the HTML5 spec goes to some lengths
to make implementing such a feature somewhat easier than it had been, for
example by defining what is a parse error and what is not.
