Review comment:
       I still don't agree - it seems that you are suggesting using `delete`, 
expecting its behavior to change in the future. That will bring about 
backward-compatibility issues and make the meaning of "delete" murky. Moreover, 
there's no harm in having `deleteEphemeral`.
   
   It's fine if you need to provide another endpoint/API, but a good API design 
involves something that is 1) easy to do and 2) doing exactly what it's 
advertising to do. Do you see why I think it might be less desirable to add 
hidden assumptions to `delete`?
