Er, what?

The *only* part of this whole enterprise that actually seemed to make
even a tiny bit of sense — rather than seeming like a thinly veiled
retrospective excuse for dragging us back in time by 30 years — was the
bit about making it easier to grep.

But if I understand you correctly, you're talking about using something
like C trigraphs to represent the perfectly reasonable text emdash
character ("—") as two hyphen-minuses ("--") in the source code of the
documentation? Isn't that going to achieve precisely the *opposite*? If
I select some text in the HTML output of the docs and then search for
it in the source code, that's going to *stop* it matching my search?
