Oh yes, I understand this.

There are some small applications that never pass domain names around
except to/from the user and to/from DNS (like ping and netstat, and
telnet I think).  For these applications, changing gethostbyname() to
support the encoding of the current locale might be enough (if they are
already 8-bit clean).

But application-layer protocols do indeed need to define a common
representation of domain names and convert between that and the local
charset.
