I don’t want to change my project’s established conventions and clutter my git logs because arc wants to scatter droppings all over my commit messages.

It sounds like Phabricator isn't a very good fit for your project. You can find some alternatives on Wikipedia.

Another example would be the ‘Summary:’ heading — git commit message formatting already defines what the summary and body of the commit message are.

I second this request, although if it could be fixed in a way which avoids adding another configuration option, that would be great (I agree with T8227).
