Yes, but not yet, which is all CERN needs for now.

They'll undoubtedly switch to something else in a few years if they continue to favour hardware retention over software compliance.

Spiralling off into rampant speculation, I can imagine they might end up finding some way to create their own in-house Linux distro that supports old hardware if all the stock distros raise the bar out of the reach of what they have, but I'm sure they hope that's a way off yet.

But it could be a good thing for folks outside CERN with old hardware if that ever comes to pass.
