Making open source projects accessible with Vagrant

Perhaps one day providing the develop environment's definition in the form of a Vagrant VM (or, probably better, a Dockerfile) will be as common sense as providing README and LICENSE files.
I would hope this becomes a trend. I was very happy when Discourse first went open source and included a Vagrantfile for development in their git repo, made getting up and running much easier (especially since I'm running on windows a majority of the time and certain libraries don't always play nice).
