This is a great point. I thought about how I could simulate commands like "git pull" and "git push", but like you said that would require communicating with the remote to determine ... stuff ... like what objects need to be synched, and potentially even doing some of the actual data transfer before an accurate simulation would be possible.

My initial goals for this tool are to purely simulate actions on Git repos without actually modifying them, but I might be flexible on that going forward, as I mention in the article with the --execute flag.
