Generally, the only macros which are allowed in tournaments are those which the game lets you set within the in-game options menu.
SSF2X has no such function. One could argue that the console releases versions of this game had that feature, but it's a weak argument.
SSF2X is a game which is still played with the idea that players should try to adhere to the arcade standard.
In recent years western tournaments have started using cabinets for the game again due to this preference among the majority of players.

Now, a duplicate button isn't exactly a macro by definition, but it's function is attempting to do the same thing: make your inputs easier than using the standard minimum button set.
Having duplicate buttons helps with pianoing as mentioned. It would also help with hitting PPP and KKK moves. Things it would affect

Zangief: Spinning Lariat
Claw: Backflip
T. Hawk: Condor Dive
Boxer: Turn Punch
Dhalsim: Teleport
Honda: Hundred Hand Slap
Chun-li: Lightning Legs Kick
Blanka: Electricity
All Characters: mashing in/out of throws.

It's a small edge, but one which should be banned because there's no real downside to using it. Which means that if you want to be competitive in SSF2X you need an 8 button controller.

But why stop there? Boxer in particular would probably benefit from a 12 button controller to allow unusual hand positions while still charging turn punch. Which would make a character who is already top tier nearly unstoppable.
