We pay money to play this game. Everyone should have the choice to back out of a lobby for whatever reason they choose.
I back out when my team has a human goalie against an AI one. I also back out of a dressing room if I have an AI or two Dman because everyone knows how much they suck. I back out of a lobby against a team of “sweats” etc. I’ll also back out if one of my teammates backs out because I don’t play with AI unless it’s two AI goalies.
There are several good reasons to back out of dressing rooms and lobbies if I know the game isn’t going to be enjoyable to my standard.
