All this talk of applications that flag for human intervention when
incomprehensible data appears might just be acceptable when the
application is a big installation that has a dedicated support staff
anyway, but when it's something like:

...a web browser that gets deployed on millions of random machines all
over the place, then instead you get developers having to test their
HTML against a list of major browsers, and being wary about including
things like MathML, SVG, Java, Flash, etc. in their sites. It appears
that "in the large", these kinds of systems tend to end up constraining
the producers of content to a schema ("works in IE") anyway.
