This is very you/your-industry centric.

There are several implementations for HTML rendering for output to PDF
and other document formats. Companies have built products based on it.

You seem to misunderstand the diversity of a free market.

Consider that a company might start-up, with the intention of creating
another HTML to PDF rendering utility; or a rendering utility for some 
other format.

By implementing in ECMAScript, they may indeed have a head-start against
other companies implementing in C++;  though ecmascripten and NaCl
are great projects, I'd see greater success sticking to ECMAScript and 
Canvas
to implement with.

Why would you say that out loud Tab? The world is hard enough as it is.
It pains me to see this kind of thinking applied to such important 
decisions.

I should not have to defend free enterprise to developers on a web
standards mailing list.
