The main point is that 2to3 as a strategy for "straddling" python2 and
python3 is a showstopper for folks who actually need to straddle (as
opposed to one-time conversion):

- - 2to3 erformance on large projects sucks.

- - 2to3 introduces oddities in testing, coverage, etc.

- - 2to3 creates problems with stack traces / bug reports from Py3k users.

There are a *lot* of folks who have abandoned 2to3 in favor of "single
codebase": the PEP addresses one of the last remaining issues to making
such codebases clean and easy to maintain (the sys.exec_info hack is not
needed in Python >= 2.6).
