I'm certainly in favor of keeping the stamina bar away. It was only an annoyance, nothing more. You'd get stuck on every little piece of rubble and when you finally needed it it was all out.
Infinite/finite stamina has no effect on bunny hopping. Even with the stamina bar empty, you could still jump. It only prevented sprint jumping. People have been bunny hopping the same amount ever since the release of the mod. The only people who I see doing it frequently are new players, who have probably gotten it from other games. And so what if they do it, they're only making themselves easier targets by jumping up and down. If you look at any of the older experienced players, none of them do it, because they know it useless.
