The ecosystem makes it more difficult to write bad software. Handle all of your errors, you can't put in things you don't use, it makes testing VERY easy, logging really easy, and if you have testing you have performance testing for free with it.

Not having version management is a real concern, but I solve that problem by forking the projects and updating manually as needed. Ubuntu and debian are soon going to be allowing you to install go packages with their package management systems if I'm not mistaken.
