That will cause lots of trouble in normal networking situations, e.g.:

server	ether 0		192.168.1.1
	ether 1		192.168.2.1

client	ether 0		192.168.2.2

If "client" tries to connect to 192.168.1.1 (e.g. because "server" has
A records for both interfaces) the connection will fail although
everything works as expected.

See above.
