I think live on the board game is a very different scenario with respect to Lichess online. In a vis-à-vis situation any comment can be ok.
Online, the "good game well played" message is definitely rude because it is a dumb automatism, completely detached from what happened in the game. No reply is expected but it calls the other player to open their chat window just to read a meaningless standard line, like a fortune cookie, always the same, that we are forced to read hundreds of times. Useless and irritating, expecially on Lichess app. Very bad idea to implement such a nasty automatism.
