Thanks for being part of the GoDaddy Community! Great question.
I'm not a developer, so I can't completely answer your question. However, I can let you know that we have a builder in the works that is "mobile first". It will allow users to build and manage their website using a mobile device or desktop. My guess is that we're putting our development resources toward that rather than into GoMobile.
