Honestly I think that, like version control, time estimation can be a very useful feature for people working on a project alone if they use something like Joel Spolsky's evidence-based scheduling[1]. It would be nice if GitHub provided a way to keep track of that. I agree with you that there's a point where there get to be too many features, but if they're building a project for teams to work on things time estimation seems too useful to pass up.

There are a number of time-tracking tools that interface with GitHub via it's API.
