That sounds like a good solution going forward.

Doh! That's actually a very illuminating question... One which, had I
thought of it earlier, I might have never thought of dealing with $ at
all... ;)
Basically anything that is meaningful markup in TeX would have to be
escaped for usetex, but not for regular text. In that sense, $ is just
one of many. Think of "{brackets}", for instance. You get "{brackets}"
with regular text, and "brackets" with usetex. I'm sure the list of
these things is fairly long. We don't want to start implicitly escaping
those for usetex. All this supports the theory that perhaps the gap
between regular text and usetex is too wide to reasonably bridge.
While originally this morning thought "let's just fix the
inconsistencies", I'm now leaning to just adding a note to the docs that
"regular text and usetex is fundamentally incompatible in a lot of ways"
and leaving it at that.
