Did you check where this was called ? Is the default valid ?

Also: how to force it to not reuse etags ? Maybe introduce a new "FORCE" constant ? (passing 0 is not so intuitive)

From my POV we shall always reuse the existing etag - we might even want to drop some code with respect to this. Nevertheless this might help in some edge cases 👍

Code looks good... 👍 if Jenkins passes.
