[deleted] I don't remember exactly which reasons let to the development of this extension, but it's not a very optimal way of solving any problem.
When using Cloudflare, the same kind of rule builder is built-in into Cloudflare and is a lot better for performance as your server is never reached.
For migrations, this tool isn't useful as there's usually a need to interpolate slugs to IDs or other things. For that reason I prefer building custom extensions for the redirects of each kind of imported platform.
For basic redirects, Apache/nginx are way more performant as they don't require booting Flarum.
For protocol or www redirects, Apache/nginx rewrites or the Canonical Url extension can be used.
I'm currently not seeing any situation where I would recommend using this extension over other more performant solutions, as such I'm not seeing any reason to revive this extension.
I'm happy to hear any use case that would warrant an update.
