Of course not, the kernel already provides everything needed for years, and
these dummy apps can still request bindv6only to 0 on the sockets they listen
on their own, which is also discussed at debian-ctte:
int b = 0;
if (setsockopt(s, IPPROTO_IPV6, IPV6_V6ONLY, (char *)&b, sizeof(b))==-1)
they would be still inferior to those opening two separate sockets (which
means more fine-grained control like listening on v4 or v6 or both, or
establish means to threat them specifically if necessary), but this is at least
easily doable for brain-damaged apps badly in need for 0.
