Simplicity is key in designing these sorts of things. It just makes the system seem a little sloppier than it needs to be. What would be the advantage of keeping both?
/u/ would be consistent with tribes (/t/) and reddit, @ would be consistent with everything else. If anything it's less confusing because it covers the two most common notations a new user might try to use. I know software that supports several different notations and I never saw anyone confused with it.

I suppose in the end it's up to the devs. I still personally think it's better to have one or the other, but that doesn't discount anything.
