Fine. But if someone knows to use mergetool, they probably don't have a problem to begin with. My concern is for all of the junior developers out there who are getting conflicts with terrible default conflict marker style and are struggling through it because they didn't know there was a better option. Educating everyone on how to use `git mergetool` would be great but it is hard. Changing the default so that conflict markers is understandable is easy and benefits everyone.
