One case that could be broken would be a user having already another
service listening on ipv6-only along qemu listening on ipv4-only. But I
find this very little probable.

"0.0.0.0" would get ipv4 addr-any.
Without anything done in particular, "::" would get both ipv6 and
ipv4. We could make libslirp enable the IPV6ONLY flag to avoid that, and
make qemu pass an AF_UNSPEC address for the ipv4+ipv6 case, in which
case libslirp wouldn't set IPV6ONLY.
make that ipv6-only through a flag passed to

I'd say so, yes.
