He argues that underflow/overflow are usually caused by bugs in the code. Having so many special numbers implies reducing the numeric representation (there are a lot of NaN in IEEE-754) and a hardware overhead to deal with all the special cases. That small hardware overhead can add up when working with thousands of FPU.
The vast majority of application dosen't need fine control of the FPU. There is always will be hardware for the few application need the ieee-754 features.
