What downside might there be for substituting stainless nozzles for brass? For everything?

Heat transfer in stainless steel sucks compared to brass. If trying to print fast, I could imagine a situation where the tip of the nozzle cannot maintain temperature as the plastic passing through it draws out the heat - and transfer through the material can't keep up with the demand.

Thermal conductivity of yellow brass is about 9x that of 303 stainless.
