Any way to get the GID of the owner of the file automatically?

I think it'd be nice to NOT specify the group of the key files and use the primary group of the user that owns the file. Currently, not specifying the group of the file causes the module to assume (incorrectly some times) that the owner and group are the same.

Exporting every user's primary group is a trivial addition and would solve the issue.
