I'm going to go ahead and say there is no point of Chidori, and the chances of it being implemented separately from Raiton Ninjutsu is 1/1,000,000.
There is already Raikiri Essen, and some other Raikiri like moves in Raiton. And the reason Rasengan is separate, is probably because it has no speciifc chakra nature, so it can't be grouped with anything. Chidori is just about the same thing as Raikiri, and to separate it from Raiton would be unfair. Especially to put it in Uchiha.
And no, Uchiha / Lotus doesn't have any special moves whatsoever. I am maxed on both, and nothing is there that is special. At all.
Chidori, all in all, is just a Raiton move. Anyone with great stamina and agility could learn it, but it takes such movement perception as Sharingan to actually not get hit, due to have to move in practically a straight line. So, there's no point in having Chidori implemented. Try again with something liek Tajuu Kage Bunshin. That would be cool.
