Yeah, that's not the ideal way to present the idea of a spandrel -- it's more that a trait evolved not due to direct selection on the trait itself but as an indirect result of the evolution of other traits. But yes, even traits under direct selection aren't "specifically sought" by evolution -- it's just a consequence of variation plus differential reproductive success -- there's no active seeking going on.
