Because as per Company of Heroes design, even back in vCoH, all "abilities" cost munitions. It's already been suggested and the reasons have been stated as to why it won't work that way.
That's actually not a good enough reason. In Coh1, all off map abilities cost munitions (unless you count overdrive for the Cromwell). In Coh2, relic has added abilities that cost fuel. (The "breakthrough" ability for the encirclement doctrine). Munitions for abilities may be the norm, but that does not mean that it is the rule. If you have evidence (such as a statement) from a dev or other relic employee that no abilities are allowed to cost fuel, then I will accept that conclusion.
I personally have started playing lots of OKW since WFA, and I believe that combat blitz and blitz need a rework overall, as they are just stupid broken in terms of the cost/ function of their useage. It is an ability which allows one to take the best armored units in the game, and then give them both a "get out of jail free card" and a way to chase own wounded enemy armor that does not benefit from such bonuses. It even flat out negates the advantage that allied armor supposedly has, which is mobility.
