   CERN spoke at DebConf [1] and indicated that ~47% of their accelerator   
   control fleet runs x86-64-v1, which due to a cascading series of   
   replacement costs meant that they estimated a budget of about €7M to   
   migrate from CentOS 7 to CentOS Streams 9.  As a result they chose to   
   switch to Debian instead, and they said that their plan A was to use   
   trixie and upgrade to forky in 2030.  If I understood them correctly,   
   they did say (in the Q&A) that there was a plan to upgrade to at least   
   x86-64-v2 in the 2034 long shutdown, but that it was still a complex   
   project with the possibility of being derailed by operational issues.   
      
   Has anyone consulted with them about how this would affect their plans?   
   They're a pretty significant organization and I know a lot of Debian   
   developers would like to keep them being able to use Debian.
