I mean a solid code is definitely an excellent thing but idk it seems weird to me to focus that much on it right now especially when your game is still barebones content wise. Code updates won't help you build a fanbase, which this game really needs. It's been here for almost a year and a half and it barely had any progression content wise since the initial release, if a few extra renders at some point (assuming 2.0 really doesn't include anything new as depicted in the changelog, I haven't played it).
I hope you are right and that dev can now fully focus on creating new content.
Edit:
