It's not sub-optimal w.r.t. link bandwidth, if the link is
a broadcast domain. Moreover, broadcast is no worse than
all-node multicast.

And, given the CATENET model of the Internet to connect
broadcast domains including small number of devices by
routers, over which there is no broadcast, that is a
sub-optimal operation.

In this thread, there is an example of such an operation to
have a lot of WiFi base stations with omnidirectional antennas
at full power.

No protocol can be fool proof against sub-optimal operations.
