Gamerule Suggestion/Request - sprintHungerValue / swimHungerValue

Combat snapshot 5    -Sprinting is no longer affected by the food value
Combat Snapshot 6    -By popular request - Reintroduced the rule that sprinting requires more than 6 points of food

I really liked not being sprint penalized for being hungry.
By default with all the changes by Combat snapshot 8 I agree with the decision, but i would love to see a gamerule in the basegame for being able to sprint until no hunger remains or maybe even beyond.
Could set it up as a variable gamerule perhaps, how much hunger is needed to sprint, 0-20+, and 0 or -1 for infinite sprint.
exmaple: /gamerule sprintHungerValue 3

Sidenote, it would be awesome if there was also a rule like this for swimming.
/gamerule swimHungerValue ?
