There is a mapping from Git SHAs to Hg SHAs. Technically we could add a command to run an Hg log from a Git SHA since we have a one to one mapping, but it's generally easier to not have to really know what the Git stuff is. You should be able to work in Hg with all your normal workflow, but push and pull from a server with a git+ssh protocol instead of an Hg server. It should be mostly transparent for the Hg user, and a developer using a Git client should not be able to tell that commits authored by an Hg developer was even using Hg. The data stored by both systems are not hugely different.
