I'm also happy with the freedom and stability of a single-purpose static site generator. My previous project, Tclssg, was public and reusable from the start. This had big upsides: I learned to work with users and was compelled to implement features I wouldn't have. I actually wrote documentation. Seeing others use it was one of the best parts of the work. However, it also put constraints on what I could do. I couldn't easily throw away or radically change features, like how templates are rendered by default. With an SSG that's only for my site, I can.

If I were maintaining multiple large sites or working with many collaborators, I'd rely on something standard or extract and publish my SSG. For a personal site, I believe custom is often better.

The current generator is around 900 SLOC of Python and 700 of Pandoc Lua. The biggest threats to stability have been my own rewrites and experimentation, like porting from Clojure to Python. I have documented its history on my site: https://dbohdan.com/about#technical-history.
