I suppose you could remove it.
But I know of no faster way for me to uninstall it and resolve never to spend another dime on a DCS module.
I have a wife, 2 children, a full-time job, and graduate school. I do not have tremendous amounts of time to dedicate to learning what amounts to a systems simulator when what I want to do is fire up a jet and make something go kaboom. I'm perfectly aware I'm firmly in the minority.
It is entirely possible that DCS could remove this feature, I would uninstall the product, never purchase another DCS product, and DCS would never even notice it happened. I'm okay with that. I've stopped using other products when something about it changed and it no longer suited my purposes and I'm pretty sure that news of my decision would've come as a complete surprise to the manufacturer. My Motorola MotoX phone comes to mind.
So, remove it, don't remove it, it makes no difference to me; it's just a game. For those concerned that it is taking up valuable development resources, you needn't worry; very few of the aircraft in DCS can even use it properly. The A-10C and the Russian aircraft in FC3 have functional game avionics and flight models, the rest of them haven't been able to use it for more than two years and the myriad of patches in that time have not addressed their shortcomings, so I think y'all are safe from people like me. It doesn't look like it's on ED's list of priorities.
Just one more thing to consider before I go: Ace Combat 7 is going to outsell DCS. By a large margin. Not that I prefer Ace Combat games (I don't), but that's just the reality.
