why would you want to that?

So I can add metadata to them 😇 or rather, so I get a list of pages without metadata to give to the person who will define the metadata

you can just store it in the database and store pages that has metadata in that case

any person can set the metadata in which it will be reflected on the next request

Yes, that's how I do it for pages with "slugs", but we have so many other pages which aren't generated from data and I wanted to generate an overview of them, and in the long term have a check for it as part of my CI pipeline

That gave me an idea, even though you removed it

Maybe I can on every page just do export const generateMetadata = metadataFactory() and just deduce the path inside that function
