   > @zeekling is the change acceptable?

   > FWIW I'm thinking we may want to do a 3.5 release with compatibility

   I support this decision +1.
   
   I support the removal of HBase 1.x in the Hadoop 3.4 branch, as the official 
stable version of HBase no longer includes 1.x. We should move forward. If 
users need HBase 1.x, they can utilize previous branches (Hadoop 3.x) and make 
adaptations suitable for their internal production systems.

   ```
   1.0 was EOM'd January 2016; 1.1 was EOM'd December 2017; 1.2 was EOM'd June 
2019; 1.3 was EOM'd in August 2020; 1.4 was EOM'd in October 2021; 1.x was 
EOM'd in August 2022
   ```
