Windows 10: Why is .NET Framework 3.5 not installed by default?

I've always wondered why would Microsoft not have it preinstalled and need people to install it manually? I was under the impression that I always have to install it since sooner or later some program may not run or install if it's missing.

Just want to correct my understanding about this, is there any downside of installing it or any reason you can think of why Microsoft doesn't integrate it by default in the OS?
