Presumably, OBS makes building for additional architectures not too big of a deal - although I realize it increases kernel and testing somewhat.
the big deal is in the amount of build capacity needed and the maintenance and work it is to keep track of all this.
Build capacity is trivial on X86 side. And what maintenance work exactly? I'm certain that all code that compiles atom-tuned compiles without any work on generic X86 as well. Having multiple ARM build variants has been easy for MER using OBS, and I'm sure it is even less work for generic x86 vs core2-tuned..
on the x86 side, I kinda disagree with your choices. Every linux distribution to date picks one "start point" in the x86 evolution, and supports everything after that. Right now, MeeGo uses "Core2Duo" as that starting point (which is now 4 years old or so), which includes Atom as well.....
But Cpu's without SSSE3 didn't exactly disappear from market 4 years ago.. they are still on sale! And many people haven't bothered upgrading their PC's for last 4 years either.
