Is there any system which builds from unmodified glibc sources, without 
any local changes and backports, and promises to remain this way for the 
future?

I don't think so.

Even if we had point releases, you'd still have to check the 
corresponding sources to see what the local modifications are.  Point 
releases really do not help you here.

Thanks,
