Yes, it's an issue that can't simply be ignored for lack of a universal
definition. Words exist in many languages used on the web, we should be able
to style them.

Agreed. Also first-n-lines.

Another (and more commonly used IMHO) styling effect is to to differentiate
the first n words that are within (or intersect with) a given geometric
region. For example, in books and magazines the first 2 inches of words on
the first line are often bold.

This might also be done via a pseudo element, for instance (feel free to
suggest a better name):

p::leading-box { width: 2in; font-weight: bold; }

or

p::leading-box { width: 50%; font-weight: bold; }

The leading box could default to the first line if not otherwise specified.
And no, you wouldn't break words with this box, nobody styles half a word
like that. The box would grow as needed to enclose the last word that
started within it.
