[Rd] formal process for orphaning a package

[Max Kuhn]

The CRAN policy page
(https://cran.r-project.org/web/packages/policies.html) implies that
there is a formal procedure for orphaning a package but none is
mentioned in the Extensions manual
(https://cran.r-project.org/doc/manuals/r-devel/R-exts.html).

This page (https://cran.r-project.org/src/contrib/Orphaned/README)
implies that one would simply resubmit the package to CRAN with the
text "ORPHANED" in the `Maintainer` field.

Is this the case?

If this is not documented somewhere, can it be added to the Extensions manual?

Thanks,

Max
