   What about riscv64, is that going to make the same switch as Ubuntu (RV23)?   
      
   And any plans for loong64 yet? The port is very mature these days and we have   
   two beefy loong64 machines under the supervision of DSA. It's a very good   
   candidate for forky in my opinion.

   I think dropping POWER8 is a bit early given that POWER9 is just three years   
   younger.

   Do we have any sort of feedback what machines users run Debian's s390x port on?   
      
   I would argue that both POWER and z-Series are hardware with very long support   
   cycles by the manufacturer, so I think the baselines should be moved at a   
   slower   
   pace compared to x86_64 where acquiring new hardware also doesn't cost a   
   fortune.   
      
   Thanks,
