People have wanted this for yeeeeeeeears. Speaking as someone who's currently happy with my horns and face, I agree with you OP. More customization options are a good thing. It would be nice to have this. There's no reason not to.
Now, because it's these forums, prepare for people who come in and tell you why you don't actually need this, or why they think it's ugly so nobody else should be allowed to have it, or why SE is simply too small and too indie to even consider it, or that there are other more pressing things for the team to deal with first (why can't they do both?). Bonus points when people who have as much knowledge about the game's programming as you or I come in to try and give a tech explanation of why some QoL feature is "not possible" only for it to get implemented a year later or something (looking at you, guy who told me overmelding couldn't be automated like it is today because of technical debt only for them to implement it; had enough of the LARPing-developer excuses tbh).

Anyway, bumping to show support even though you're literally better off screaming about this in the xiv discord or just @ing the company on twitter since nobody important checks this place.
