It would require changes to the existing code (see below).

Actually, in the sockets API to listen on "all configured addresses"
you specify the "wildcard" address (0.0.0.0). There is no call to
"listen on this list of addresses". What you are looking for could be
done, but it would require multiple listening sockets, one for each
address, which (as far as I know) the code doesn't currently do.
