Sounds like a decision to split a module into a package is a big commitment.  Each of the individual file names becomes a permanent part of the API.  Even future additional splits are precluded because it might break someones dotted import (i.e. not a single function can be moved between those files -- once in unittest.utils, alway in unittest.utils).

Can Python 2.7 pickles containing unittest classes be unpickled using 2.6 or earlier? Even if nobody uses the new names for imports, I believe they implicitly end up included in any pickles involving affected classes (I seem to recall we've been bitten by that before when moving things around).

Cheers, Nick.
