As of Arma 3 version 1.38 you can safely remove mission event handlers without worrying about decrementing higher indices.
EDIT: this command used to decrement other EH ids above the deleted one (e.g EH 0,1,2,3, delete EH 1, EH would be 0,1,2 now and not 0,2,3) - Lou Montana (talk) 19:29, 25 June 2020 (CEST)
