It seems to me there are a couple of possible directions with logger and project-manager:
1) Merge logger into project-manager. Allow logging with projects, and perhaps the option to not do so. I'll definitely need some help with this.
2) Keep logger as a separate package, and perhaps write upgrade scripts to allow people to move over if anyone had the need for this?
2a) Project manager could be totally separate from logger.
2b) Project manager could try to integrate in some way with logger, by calling a new API or something.
There are some big disadvantages to keeping them separate, but I can see why some would want that.
It's also some work to merge them.
