Some controversial checkins have not been discussed beforehand.  I watch 
the checkins, and I see things that I don't like, but I don't pipe up 
unless I consider the checkin dangerous.  I usually give people the 
benefit of the doubt.

In the case of empty Etags, I think that sending an empty header has 
been shown to be the wrong choice.  I suggest it should be removed from 
the head and the 2_7 branch.

For future reference to any committers: if you modify any HTTP headers 
sent by Zope, you very likely ought to discuss it before checking it in.
