To specify, I was refering to x86-64-v1 hw when I said "reasonably large amount of users". As I wrote already, that hw is still in mainstream use in the form of used Core2Duo-era office PCs that gained a second life as someone's home PC.Yes, 20 year old hardware is looking ancient and retro.Except for homelabers, in enterprise environments (legacy software!) or lab environments (specialised hardware peripherals), etc.There is no practical reason to use Linux on any of those [...]
FYI: CERN has started to look into replacing RHEL with Debian on the Front End Computers of the Large Hadron Collider (LHC) especially *because* ~ 50% of the installed hardware does only provide support for x86_64-v1 and cannot be operated with RHEL9 and above. This hardware is essential for keeping the LHC running (at least until 2035?) and operating it with RHEL 7 until then is apparently not feasible.
See https://indico.cern.ch/event/1477299/contributions/6363918/attachments/3044399/5378883/20250403-HEPiX-cern-els7.pdf (esp. slide 7 and slide 34)
So dropping x86_64-v1 would be a bummer for them – and probably also for Debian?
