Should we consider double setup "legit"

[Xtreme2252]

I don't understand any of the fuss about double setup. Anyone can do it with one keyboard, which means it doesn't give people an unfair advantage and it is awkward to do in the first place, or else it would be acceptable because everyone would do it. I recall having this conversation with a certain someone in particular who said double setup is equivalent to using a modded controller, or even botting. It is not in any way similar, and many old charts are nearly clearly charted for double setup (Crowdpleaser, RunnyMornings (SGX Mix), AIM Anthem!!!!111111oneoneone111!!!11, Revolutionary Etude, or the joke file vROFL). True that these are all technically possible to AAA (minus vROFL) with spread, but due to awkward layering or sometimes blatant overcharting they are artificially difficult. If you submitted a chart like that nowadays the judges would ip track you, chop off your head and then kick it around like a hackysack, and really no one could blame them for it.
