edit for clarity: i'm just saying it doesn't make sense that a manufacturer would put out such a product
It makes sense, but mainly for a specific application. I've seen spin bike pedals with cages on one side and SPD-SL (or maybe Look) clips on the other. We found them online sometime a year or two ago and posted them here on BF, too.
Aha!

Basically, they're a combination SPD-SL and SPD pedal, then an optional plastic cage platform clips into the SPD-SL side. Good for indoor spinning classes because they're likely to work with anything.
