It has one small side effect: it will potentially move the goose if the LBL is "executed".

But I think most people can live with that - I typically use LBL 00 myself.

If speed is wanted, as in this Fastest NOP case, leaving the goose merrily fly is a bad idea as it usually entails many display refreshes which somewhat slow down program execution (most noticeable in some emulators). I always have my programs execute "WAIT...", AVIEW at the very beginning to get rid of the goose for good. Looks more "pro" too.

P.S.: It seems DM42 creators also noticed this because in DM42 you can clear a specific bit in variable RefLCD to disable the goose flight and so avoid the slowdown altogether.
