It was added when randomphoenix03 was the only active mod (is my theory not 100% sure), and if you look at his No WW run he kinda needed it lol. For everything but Warpless you're not gonna have a competitive time if you die anyways, so it doesn't really matter too much. And for Warpless it just allows people to complete the pack and submit without worrying about being perfect, so I think it might be more friendly to new players. I'm the only active player/mod rn, so I don't have a reason to change it since nobody else is submitting times. If more people joined the community and ran the game and wanted it changed I would have no problem with that.

Mari0 SMB map pack is small. Speedruns small too. This inf lives won't help you for beating WR or PB. Just can help if player very bad runner and dies on the first goomba 5 times in a row
