I don't think you did grasp the point. There's an additional level of
literal-parsing and backslash-stripping involved in the jsonpath case,
because the jsonpath path string contains an embedded string literal,
which has to have some kind of escaping behavior. Otherwise, how could
you search for a pattern that includes a double-quote?

The underlying regex behavior is the same either way; it's the surface
syntax that's different because of the extra parsing layer.
