By "more customization", it was expected more control over options, not anything crazy like adding tails or making Viera anything other than Viera. Like how you can't actually have a Viera diadem without choosing one specific hairstyle, or control ear spots (like how the Viera in XII have points without "highlights" in their hair). Hell, even a selection of tattoos uncoupled from face type would have made me go, "Wow, that is different and an extra!"
We both often bicker about semantics, but gender locked? Yes, at launch. Hatless? Understandable given the head shapes. None of these things scream Limited Race, but given in the bin of all else that we just don't have? Well, I'd really like to see an official statement on SE's intent being to make limited races when all likelihood points to development being pushed way back due to... all that going on and a bag of chips.
