   Thanks for the updates @Myasuka 
   
   There are still some questions open, please see the comments above.
   
   Besides that, can you please list some IT cases covering checkpoint cancelation in the description?
    
   I'm a bit concerned about the following scenarios:
   1. a barrier arrives for an already canceled checkpoint; alignment still happens as usual but the result is discarded, right?
   2. recently, upstream tasks started to block in aligned mode (#11351). With this change, they still will be unblocked by the downstream despite of cancelation via RPC, right?
