Primals as mounts

So I was thinking about this for a while, but I feel that FFXIV is pretty grounded in it's "flashiness" regarding armor sets, weapons, mounts, and other aspects. However, in endwalker, we've started seeing some more crazy VFX such as the relic weapons, some cool armor sets from the raids (Abyssos armor), etc. But I feel that there should be more ways to show off how far you've come in the game.

One thing I would REALLY like to see are primals as mounts, and I'm pretty sure they can make it work from a lore perspective if needed, be they robots, or creations that just look alike. But imagine riding an ifrit, titan or other mounts like ultima. I feel that this type of reward would really fit in the unreal difficulty to make it gain more traction. Or even the criterion savage dungeons, as the rewards currently feel lacking.

What do you guys think? I think it has game benefits as well as just looking cool :)
