It's also invasive, since either way, all code in all of sage that prints "I" will print using what you change it to. However, an additional benefit to having a function like sage.calculus.imaginary_i is that it will work even if (in fact, when) the "I" constant gets rewritten in Cython, which would make changing the _repr_ function impossible.
