Yes, I understood that.
However, I think developing "in the dark" is not the best idea for the future of VestaCP (after the rewrite).
You can create an "alpha" or "beta" branch on github which differs from the master branch and is for rewriting existing code which doesn't land in production. This could also be a test bed for contributions by other people on github so they can be tested and don't land in the master branch immediately.
You could also leverage the tags and releases from github to make the whole development process more streamlined. What do you think about that? At the moment the github repository and development process is pretty suboptimal, in my opinion.
