I understand the motivation but this still results in an ambiguous state if two different people check out your package from svn at different times today (before and after your changes). 

Version numbers are cheap, so if version 1.2.3 exists for a day before version 1.2.4 (which contains all the changes you want to push to your users) then that's ok, IMO.

Including a version bump doesn't impact whether or not you can rollback a commit with svn.
