At least Mojang could make separate console like: '/gamerule FireStayAlive' and that would make them to not extinguish naturally. Then I would be satisfied.
doFireTick is console command in game that make fire to not spread, it write like this: "/gamerule doFiretick", but it makes fire to not extinguish natural. In wiki is said that this command only make fire spread on or off, nothing about keeping fire like on Netherrack.
