Infinite fire spread gamerule

I think it would be very cool to add a gamerule where you could control the intensity of fire spread so that it could spread faster or slower depending on what number you type into the gamerule. For instance, if you type /gamerule firespreadpower 100, it would spread infinitely, or at least to however many blocks it can burn; but if you type /gamerule firespreadpower 50, the fire would loose power each time it spread and would eventually stop (just like how it is in the current game).

With all of the new /gamerule adds, I think this would be a good edition.
