The distributed nature of Git makes it easy to maintain my local patches that Git will attempt to use even against newer versions of Arc as they get released and other folks would be able for example to pull in changes from my repo (and I could from theirs) if it solved an urgent problem before PG could incorporate them into the codebase. It simply makes it easier and encourages collaboration. Certainly not necessary however. Maybe I should create a repository and mirror PG's releases for a while.
