I think if any new character popped up and said "I mastered every martial art, and also I'm a billionaire tech genius and the world's greatest detective," people would roll their eyes. Everyone who follows Batman pretty much has to have a smaller portion of his power set.
Yeah, classically Mr. Terrific was just the ultimate jack-of-all-trades, but I think that overlapped with a couple too many other people so they leaned him into the tech more because DC actually doesn't have a lot of heroes who lean really heavily on that, at least if you exclude Ted Kord.
