Huge problem for bo7- file size

Simple issue I wanted to raise. Bo7 is the first modern zombies game that I will want to play after the year ends. Issue is the game is like 180 gigs or something. When the next cods come out, I’d probably have to delete bo7 to download it. I know some people will say “buy more storage” which is a decent solution but I imagine there’s a lot of people who don’t want to do that. imagine bo7 rereleases all the bo6 maps as a “chronicles 2”. Is this not going to be a problem?
