Yeah seems overkill. Back in the day (1990s) you'd use a serverless script in the "Personal HomePage" language.

These days you could do this in client side JS, mayhe fetch the static list from a Gitgub blob or one of the sites in the group.

This should be just a static page… Cloudflare pages are perfect for this. All updating could be done in the repo by special scripts from MD or some other files.

Why not. It's easy.
