Trope-a-Day: Non-Mammal Mammaries

Non-Mammal Mammaries: Averted, except in the highly specialized case of bioshells (emulating species in which one sex or another has, ah, notable mammary glands) built for infomorphs who prefer their sexual characteristics to match their gender-emulating code.

Assuming you don’t make the point that mammalianism is a trait that goes with the body, whatever the mind that’s in it, anyway, which is probably a more valid way to look at things in the first place.
