Stop being silly. As I already mentioned to you, just because VF has juggles and DoA has juggles and Tekken has juggles doesn't mean the high-level play in all three of the games looks the same or plays the same or requires the same skills. Same thing applies to spacing, movement, oki game and wakeups, throws, and high low mixups. It's very naive to assume that if all games have the same features, they all work the same and have the same high-level play requirements. Using just juggles as an example, you can see how, for instance, knowing the stages may be a big part of Tekken if a player wants to do wall carries and do maximum damage. Same thing when the player does early bounds to perform tech traps and confuse the opponent. The juggle system is creative. Along with this, add the other stuff AAK mentioned about juggles and you'll see that juggles in Tekken do not work the same way as DoA or VF.
Same sort of differentiation can be applied to the other stuff you listed that you are apparently assuming to be the same across the board for all three franchises.
Everything you stated can be applied vice versa for other games. Did you know that VF and DOA have a weight system in which heavier characters fall faster forcing you to completely alter your juggle? Did you know that DOA has slopes and dangerzones that give you different juggle oppertunities? Did you know that VF also allows for characters to do bounds in their combos? See the juggle system is creative in these games too and require their own knowledge and depth to fully utilize.
I mean really these mechanics aren't that different in terms of application more so execution.
