My comment was in regard to 3rd into 2nd, not 1st into 2nd as per the OP.

No, of course you don't have to. It's a synchromesh gearbox.

But you are asking a lot of your synchros if banging down really fast and 2nd is going to end up near the redline by the time the clutch is engaged again. The car will do it but eventually the synchro cone will wear out and the shifts will become notchy. Then the owner will complain that the carmaker should have built a better gearbox.

A bit of mechanical sympathy doesn't hurt.
