There's multiple problems with the school of thought of "make everything equal", and that largely comes back to how much the game avatar is "you".
I am not Miqo'te in real life, shocker. s/
However when I was given the option to edit the V1.0 character for 2.0, I made my character the same height as I am. That's about the extent of wanting anything reflect reality. I adjusted the breasts towards the smaller size, I picked a red/purple hair consistent with what I normally use for avatars, and pretty much everything else was "does it look cute?"
The default Hyur, I didn't pick because I don't pick the boring race in a game. Why not the Lalafell or Elezen, or Roe? During Beta I didn't like how the lalafells moved (it seemed like they were hovering 2 feet in the air) , I don't like the necks on the elezen, and the Roe... just wasn't cute to me.
Now, FFXV doesn't have the option to play a Miqo'te, it has a much more capable character creator, but the character I created end result looked more like Lightning from FFXIII than my FFXIV character. XV lets you create characters with different muscle definition, weight, height, etc, by initially blending two premade characters together.
I do not want to play a character that looks exactly like me. I want to play a character that is what I feel is the best representation of my personality. To that end I aim for cute and intelligent. More "realistic" looking characters tend to not be cute at all, and instead end up being various degrees of boring.
So I'm all for better character creation, but there are certain things that aren't "character" creation at all, they're just about making ERP in a game that is rated T or M without hitting the AO rating. So making any kind of changes to the crotch ("package", "camel toe", etc) is about giving people ways to ERP, nothing else. Most characters, even in cut scenes, are seen from the navel upwards. If zoomed out to a point where you can see the character's entire body, you usually will not have their crotch in the middle of the screen. Except in this game if you're a lalafell.
To that end, a game that lets players wear all the gear the game has, while having significant character creation options is better than a game that locks you into one "skin" that is more configurable, but you have to have that appearance for the entire life of the game.
At some point, I'm sure some future MMO will allow you to upload your 23andme or ancestry.com DNA to it and produce a character that is significantly more like how you actually look than deal with all the character creation knobs and levers, and even AI can look at several photos of your face and determine how to set the character creation to best get that profile and haircut. But I want this to always be an optional thing.
It's clear that FFXIV V1.0 was trying to stay under/at the T rating, because V1.0 the breast size of the characters was tied to specific presets, there was no slider. The routinely mentioned "butt slider" was never a thing, and we keep (in jest) asking for it because the original V1.0 models were more complicated and Miqo'te has a somewhat more defined butt, and all their gear took into account their tail. Adding some kind of butt adjustment to 2.x+ was never going to be a thing, but if it was, it would be something that all races and genders would have access to. It's just present gear does not take this into account, hence why we will likely never see any changes to character creation.
