Guido can overrule this, but my take is that there will be few enough
cases where this is a significant issue.  People who want to write
cross-version libraries and applications shouldn't have to deal with
suppressing the DeprecationWarning.  If we were serious about issuing a
DeprecationWarning, I think that would need to be in Python 2.6, pushing
the default of absolute imports to Python 2.7.  That seems too long a
timeline to me.

Other opinions?
