That looks like rejecting Node.js for Python.
I also think MkDocs is great (and I'm the Docusaurus maintainer), and probably even simpler, but IMHO Docusaurus is more flexible and customizable that MkDocs.
We have seen greatly customized Docusaurus docs site, looking very different one from another. The MkDocs sites I see in the wild usually looks quite the same (often using Material for MkDocs).
See some greatly customized Docusaurus sites here: https://docusaurus.io/blog/2022/08/01/announcing-docusaurus-...
I'd be curious if you could show me some MkDocs sites with that level of customization
