Have you had a chance to research the number of uses of version() in the java eco-system to determine that  the risk to existing applications will minimal?

Often an enhancement is created when there's an idea of an improvement but no resources to do the research and develop a justification. That work has to be done when someone has time.  Usually ideas are discussed on one of the many OpenJDK email aliases to validate the idea and the approach before developing the code. See the list of OpenJDK Mail lists for details.

As for moving to GitHub,  it was in part to make it easier to collaborate on the development but also to move from Mercurial to Git.
But GitHub does not replace the need for discussion on the Email Lists.
