I am fine with species lacking mechanics. Any "Humanoid" is by definition a playable character.
Even so, players might choose a feat and explain it with some narrative relating to the species, such as an Elf might become ethereal Fey, teleport, fly, turn invisible, or whatever. I especially associate superhero games with this approach. Pick a concept, then assemble whatever powers might actualize the concept.
I would probably still play the same species I do now: a species analogous to Human or Elf, or sometimes some kind of Giant or Dragon.
