Not really. There is a procedure for making non-backwards compatible 
changes. If you care deeply enough about this, you could agitate for 
Python 3.2 to raise a PendingDepreciation warning for "unexpected" escape 
sequences like \z, Python 3.3 to raise a Depreciation warning, and Python 
3.4 to treat it as an error.

It may even be possible to skip the PendingDepreciation warning and go 
straight for Depreciation warning in 3.2.
