This url - https://json-schema.org/draft/2019-09/vocab/core doesn't work

This url in the latest draft as defined here https://json-schema.org/draft/2019-09/schema. You can go to the url and check that this is one of the urls under "$vocabulary"

I could work on a PR if that works too.

this URL is just an identifier which does not correspond to a document. it sort of corresponds to the meta document at https://json-schema.org/draft/2019-09/meta/core (referenced in the allOf property of the metaschema), though I can't quite explain the relationship.

I was confused by this for a while too. I think it needs improved clarification in the spec.

I know from the spec it doesn't have to correspond to a retrievable document but this particular case looked like an oversight to me.
Plus it is actually better developer UX to be able to click in an editor on the url and get the document being referenced.

RIght now, I would have to jump through hoops to find the validation schema. Took me like 5 minutes to locate when it should have been just a click.

It doesn't correspond to a retrievable document because we don't know what to put in the document until people try to implement the vocabulary feature and tell us what should go there.
