My understanding is that even decimals still do rounding, so it doesn't give users accurate arbitrary-precision numbers. A default number format that is much slower than built-in floating point but still subject to unexpected deviation from real arithmetic numbers doesn't seem like a win for users.

It is impossible to represent all real arithmetic numbers, so it would not be that big a loss.

It gives users rounding that they're used to, from calculators etc. Floats defy common expectations. The fact that we still have to talk about this stuff is exactly the point.
