    It's true that these networks which work by broadcast consume a lot
of the bandwidth. They aren't designed for large LANs. But service
discovery is something very handy. I imagine it might be centralized
into a local DNS server, with maybe some extension of the protocol,
instead of letting every host talk to every host. I don't want to waste
time figuring out printer properties and maintaining a printer list on
my laptop. There are already too many reasons to waste time.
