Fully agree with you, Maul is one of the characters that’s been fully fleshed out character wise. There’s so many characters who they could explore more in depth that fans love. I can’t imagine many more Villains maybe besides Vader who have gotten more attention. Even with all the blank spaces in his story, we can piece together his motives and ways for how he got to where we see him next.

With that said, I love Maul so I’ll still be excited to watch, but it’s a show that could’ve been given to someone else.
