I see they are trialing a new rule in England this season to try and prevent "tactical timeouts" where keepers go down with fake injures to disrupt momentum and allow tactical reshuffles.
Unlike outfield players who were required to leave the field of play for 1 minute, there was no equivalent for the keepers, and so no consequence to the team.
This season, if the game is stopped for a goalkeeper injury, the manager has to nominate an outfield player to leave the field immediately and remain off the field for at least 1 minute after the restart.
I like the idea, but not sure if it will work in practice.
