What you say makes sense.
BUT, my experience with at least some enemy is this. They only commit a fraction of their force, usually scouts+ATGMs+snipers which can do a lot of damage before getting killed (points wise). He never has to commit more, he can just hide 80+ percent of his forces. With some lucky strikes, even if you get the VPs, he can get at least a draw. There is no incentive to commit more. The VPs (point wise) in flags are close to worthless in anything larger than a medium battle). What happens then is the other opponent says, why try to capture the VPs, I will do the same. After a battle or two, we have a handful of units from each side fighting while whole companies are hiding in the "woods".
Where if there was some strong bonus for the flags, that would create pressure to both sides to try to do something more than WW1 trenches battles.

If the "chicken" in the above battle/campaign, knew that the other player daring and capturing and holding the flags will get something more than losing tanks etc, for example either repair points or "points" toward the campaign (the points you get for winning/losing/draw), then it would make the battles in a campaign more interesting against them.
Even as an option.

All the above, IMHO.
