And I'd disagree that "batteries included" is a phrase used to describe "features"?

I would interpret "batteries included" to mean "you don't need to worry about shaving a yak to get this installed, it's all there and ready". Language is fun!

Seriously, I was so confused by this title. Batteries are necessary for basic function of a battery-powered device, they're not bells and whistles.

I'm pretty sure this phrase in tech circles was popularized by Python's moto [1], which meant to say that language ships with many features you'd have to get on your own otherwise, so to me the phrasing here was clear - you will likely not need to pull in external deps to make it useable.
