Comment (by nbruin):
It's not entirely clear to me which simplifications are "safe" and which
are not. Simplifying `x^2/x` to `x` is also not "safe" in the sense that
equality does not hold for `x=0`. In many computer algebra systems,
acceptable simplifications are not "safe" in this respect. By including a
default `unsafe=False` I'm afraid you'll be raising expectations to a
level that Sage does not attain (yet?).
