Yes.

DSA is often used in WiFI access point, etc. The user is not a
computer professional. If the WebGUI says ETH4, and the label on the
front says ETH4, they probably think the two are the same, and are
happy.

I have one box which does not have an labels on the front panels, but
the industrial sockets for Ethernet are colour coded. So the interface
names are red, blue, green, to match the socket colour, and the cable
set is also colour coded the same.

So long as it is unique, the kernel does not care. So make it easy for
the user.
