Exactly. And that is the reason why it will be very hard not to have your own CI server. The official distribution will rarely match your requirements. We all patch packages here and there. That you can only deal with in your own setting. 
All CI servers that I know (most of big development teams) face sooner or later the same thing. You might think disk space is endless or CPU but it is not. I don't know any bigger CI server that still builds all commits. It is just not possible because CPU and disk space isn't there enough. From that angle it is even more important to remove the things that aren't really needed. 
I think you are actually looking for a reliable download location and the CI server is the wrong place for it. That's why there are last successful builds. The can be copied to a download server and rest forever.

my 2 cents,
