"Obvious only in hindsight" ~= "Obvious only once known"

Neither of those things mean "obvious" (aka "self-evident") the way we usually mean it in colloquial English. Which is why your project requires some refinement in messaging.

I'm not arguing the benefit you claim isn't there, just that your statement about benefits being "numerous and obvious but only in hindsight" is not the selling point you think.
