Sure, but for any such API to be of actual value, I need to understand 
the underlying use case first, hence my question.

Could you elaborate some more on this process, especially the part about 
replacing artifacts which I assume is the reason why you want to check 
etags for outdated artifacts.

Out of curiosity, does this closure check also include existence checks 
for metadata which would be required to resolve version ranges?
