Yes.

In the case of a document like the Guide, it takes about 10 seconds on
my machine to load the document (i.e., run the modules that implement
the document), and it took about 6 seconds to render the HTML. With
your change, it takes about 4 seconds to render the HTML. The document
run time dominates, but it's still a useful improvement.

I'll push that change (along with your other patches).
