Your points are correct. I created it for myself and my use case (and I am really, really happy with how it turned out), so the target audience would be devs who have are already building their own websites, but I didn't really think about it as a product.

I also thought maybe others could get some ideas from my methodology, implementation and reasoning.

I am also thinking of ways to make this more useful for more people (more devs), most likely by adding a useable theme for it and maybe also offering my landing page codebase.
