Yeah. Round-to-nearest-even is a well-respected rule, which is why it's the default per IEEE 754. I don't see a good reason for us to switch. Even if someone advanced an argument, it would have to be a *mighty* convincing argument to justify breaking backwards compatibility here.
I do find it a little unfortunate that our numeric type does it differently than our float types. Again though, there's a huge compatibility argument against changing that now. It does give you an "out" if you really need one or the other behavior for a particular application: you can cast to numeric or float8 before casting to int.
