I can't explain it much more simply other than:
If it hasn't been in the game since it started. What makes you think constantly asking for it will get it added?
Do you mean making modules targetable explosives? If so, I wasn't the one who asked for that.
If you mean having an ammo store, well I can't really respond to that. There are lots of things that FDev have introduced since the game was started (Hull repair limpets, Heat Sink and Limpet Synthesis being just 2 of the most recent examples).
So, umm...yea.
