Do I need to print it in ABS?

The official directions from Prusa state that only the fan shroud needs to be ABS as it is so close to the hotend. The extruder body can be in PETG.

However I only had PETG at the time available to me and made the fan shroud out of PETG. So far its held but I will swap it as soon as I expect to do high temp prints.
