   It’s a long-standing TODO[1]. There is also support for multiple   
   namespaces with different expiry policies, but I suspect it’s not   
   flexible enought to meet your requirements in a sensible way.   
      
   Anyway, this is not consistent with “intentionally impossible”.  It just   
   hasn’t been implemented yet.
