What's interesting about this is chess.com allows you to stack as many pre-moves as you like but they each cost 0.1s, whereas on lichess you can only have one pre-move which is technically free but maybe not because of delay.
The worst part is they call it an intentional choice.
"First off, premoves take 0.1 seconds. That is what has been preferred and agreed upon by most professional players we have consulted on the topic. They prefer .1 to .0 for premove. This is also what other chess servers do."[1]
It's super annoying and the reason I only play blitz+ on chesscom.
That would introduce other issues I think. Since premove are cancellable/changeable, what happen if you changed at the very last moment but due to delay it did not reached the server in time?
