I proposed this upstream and got this:

   The documentation for Net::INET6Glue states that using this module
   will include all submodules, so patching Net::INET6Glue would make the
   module behave different to what originally was intended. If you only
   want INET_is_INET6 then you should include Net::INET6Glue::INET_is_INET6
   only and not Net::INET6Glue. 
   
   The warning is there because these modules
   are just an ugly hack to make older modules aware of IPv6 and the hack
   should be removed as soon one uses a module with native support for IPv6.

My motivation for touching anything here is quite low, but it would be
nice to get the autopkgtest suite to pass. I see four reverse dependencies:
  debmirror
  fex-utils
  ikiwiki-hosting-web
  ikiwiki

ikiwiki and fex-utils only use Net::INET6Glue::INET_is_INET6 so that's fine.

ikiwiki-hosting-web seems not to use it at all; #811021 filed.

debmirror is the only package that probably uses it for Net::FTP; #811020
filed.

I'm going to close this bug by disabling the use.t check for the
Net::INET6Glue and Net::INET6Glue::FTP.
