If I understood the blog post correctly, the author wants the "You will PERMANENTLY lose: All stars and watchers from the repository" to be changed to "[...] X stars and Y watchers..." Which I agree would be a better UI.
Like so often we can easily judge this by how willing we would be to accept the same behaviour in real life and I'm pretty certain that most would not accept an UI where you could e.g. just give away your house by writing the wrong adress into some form.
