It is 2021 october, why Ubuntu 20.10 Groovy Gorilla is not moved to old-releases.ubuntu.com?

The question is in the title. Official resources like https://wiki.ubuntu.com/Releases say that Ubuntu 20.10 Groovy Gorilla is EOL.
How long it will use http://archive.ubuntu.com as URL to repositories? Do you plan to remove 20.10 from https://packages.ubuntu.com/groovy/ ? And when?
Looks very confusing.
