The methods to be used will be .transform() for the encode direction and .untransform() for the decode direction.

+1, although adding this for 3.2 would need an exception to the moratorium approved (since it is adding new methods for builtin types).

+1 also. This is neither new syntax, nor, really a new feature.

Good point. We already discussed these methods in 2008 and Guido approved them back then, so perhaps that's a good argument for an exception.

Adding the same-type codecs back even without the helper methods should be fine though (less useful without the helper methods, obviously, but still valid). Agreed. The new methods would make it easier to port to Python3, though, since e.g. data.encode('hex') is easier to convert to data.transform('hex').

That would definitely be a point in favor of getting this in 3.2, with appropriate additions to 2to3.
