you're correct - vile doesn't do this.  I recall it being discussed before.
I have thought about it - here's a note from my (10,000 line) to-do list:

        20060220 should add feature for colored-fences (to make matches take
        color into account).  Also (like lynx's tagsoup) add a mode that
        controls whether a fence (group) has to be properly nested, e.g.,
        nested-fences.

That is, use the syntax highlighting as a guide.  It's "doable", but likely
to be slow(er) since there's no direct way to get the color for a given
cell (because vile uses regions...).

fwiw, vim (checked against a script I'm working on) handles curly braces
inconsistently versus quotes and regular expressions.
