We have executed "/gamerule dofiretick false" twice and have witnessed lightning nearly burn down a house, and have tested by lighting a tree with flint and steel and it spread quite fast.
So firetick ignores the false setting, and will spread in 16w40a.

Works fine for me. Make sure you are typing doFireTick
exactly as seen here. Gamerules are case sensitive.
Tested on server. The rule itself goes through, the value is set. The fire still spreads with value set to false. Test to put fire on a tree and see it burn.
Use
