The fan demand about Lloyd is just an echo-chamber thing. Harada himself (for who do not know him the Tekken director and since early 2019 General Manager at Bandai Namco) specifically stated that Tekken characters got way more requests than Tales or Gundam characters:
"The fans, rather than asking about Tales or Gundam or some of our other franchises, the fans abroad saw Tekken as one of the key words and took off on that," he says. "We're not really sure at this moment but when thinking of the playerbase who is playing
Smash Bros., maybe
Tekken characters is something they wouldn't want, so I've been pulling back on that a bit. But I don't know."

And again why are there no plans for Tales of Arise on Switch if Tales is so close to Nintendo? Also lmao at grasping at straws: "you don't even kmow if Lloyd was considered", neither do you as there is no evidence for it. If anything if Lloyd is such a shoe-in why hasn't he appeared before? If he is so supported and easy to implement? Heihachi ast least has the excuse that it takes time to develop his complex moveset? But Floyd from Fails of Symphonia? Sure has nothing going for him.
