I drew this conclusion from "If an implementation does not support denormalized 
values", because it somehow implies that you do not have to implement gradual 
underflow anymore if your hardware does not support it or if it has a faster 
flush-to-zero option.

It could be a non-normative note intended as a hint for implementations that 
are not intending to be fully conforming to the standard, but then that 
intention would need to be clear.
