I don't see how git can be considered given poor windows support -
compilation on OS/X can be a bear too.

And I echo the need/want to be able to customize the workflow and
integration with the tracker/etc with something a bit more flexible.
The bzr plugin system is nice.

Also the ability to completely nuke the local-work-copies commit
history ("cleaning it up") worries me, but I'm also paranoid.
