True. but if you're far out, you would almost certainty starve before you get to the spawn. Using mobs that want to kill you to light a portal is dangerous and difficult at best.
Why would you have a fire charge on you in the first place? They are an inferior version of flint and steel when used in the context of igniting a block. So why encourage using them for that? We can enable the ignite block effect, its just so ineffecient. The only real use I could see is trying to kill enough mobs in the nether to gain the materials to make one to get out... but you would have better luck just getting a ghast to reignite the portal for you.
I would view getting a Ghast to reignite the portal much much easier than getting lucky enough to even find a nether fort near where you are, then killing enough mobs to get the items. We also will never enable firing from dispensers. It's too much code to support that.
would it be possible to only enable the sprite? like it does not catch anything or cause player dmg like snowballs. if so then i think this would solve most of the gripes about using them as decoration. i dont think their flames should be available tho
