Super Cell did in fact fix this issue in a variety of ways.
First, they increased the raw amount of loot a CC can hold. Of course, they also increased the amount of loot you get if you win so that was pleasantly offset there.
Then they came out with clan perks which allow people to level up their clans. So you can increase the amount of loot your CC can hold this way.
Generally, I cant imagine this is a problem. CCs hold so much loot now it should be nearly impossible short of someone attacking TH10s just for loot when they are TH7 and below. A TH8's CC can hold like 1.2 million in a lvl 5 clan. That should be way more than enough to hold proper loot from 1 war
