R devel - Dec 2021 - install.packages() and Additional_repositories

Dear R core team,

Writing R extensions mentions an optional 'Additional_repositories'
field
in the DESCRIPTION. (
https://cran.r-project.org/doc/manuals/R-exts.html#Package-Dependencies).
Currently, install.packages() does not use that information when installing
a package. Would you accept a patch to amend this?

If so, should install.packages() use the `Additional_repositories` when
listed? Or should that be based on an extra argument? E.g. additional_repos
= FALSE (default).

Best regards,

Thierry
