I agree with Mark that optional features/alternate behaviours make  
clients more complex and results usually in poor interoperability.  
But, boy, do I dislike ETags. They are like visits to the dentist,  
necessary but no pleasure.

How would a client cancel an upload scenario which just uses ETags?  
(With temp URIs the obvious solution seems to be a DELETE on that  
uri. I sure would feel uncomfortable with a DELETE/if-match: Etag on  
the original POST target...)
