PR #2560 uses the repo creation time to show the age. This may be confusing and misleading by tricking people into thinking it's a project age.

Some projects may migrate between code hostings over time. For example, for https://github.com/cherrypy/cherrypy Refined GitHub shows the age of 3 years while it's way older: the first commit is dated 2004 (I think the project started ~2002 but the version control doesn't have that info).

So it would be nice to have some switch to enable using the oldest commit date instead of the repo creation time.
