I believe you, but apparently I still haven't really understood the
point of the advice.

For example, I would think it's expected behaviour that "`a" in a string
produces "\(\alpha\)" with CDLaTeX; indeed, so far I thought it was just
a bug that it didn't! Likewise, that a standalone `a produces \alpha
instead of \(\alpha\). Why is this not expected behaviour in Org?
