One use case I have is : I write something like
f(x) = x if x < 10
in a displaymath environment, then I realize I forgot the \text{} macro,
and so I have to wrap x < 10 between dollars in order to get:
f(x) = x \text{if $x < 10$}
(I know that doing \text{if }x < 10 would mostly look the same, but I
can't get my eyes to accept such a thing ; and there are cases where I
can't do it, e.g. using the starred cases* environment of mathtools
which automatically sets the second column in text-style font.)
(As for the double dollars, I have nothing to add.)
