And if these clients are part of a huge network, you have to provide a
one server that talks NTPv5 for the cool clients, and another server
that provides NTPv4 for existing IoT and embedded devices?

Or you would have to provide (and maintain) an NTP server implementation
that supports both v4 and v5, depending on the version of the request.
