Yes, what is being asked for is a very thin veneer. Everything
underneath still uses master, and that is very unlikely to change. Do
we really gain anything with:

.BI master " DEVICE"
- change the DSA master (host network interface) responsible for handling the
local traffic termination of the given DSA switch user port. The selected
interface must be eligible for operating as a DSA master of the switch tree
which the DSA user port is a part of. Eligible DSA masters are those interfaces
which have an "ethernet" reference towards their firmware node in the firmware
description of the platform, or LAG (bond, team) interfaces which contain only
such interfaces as their ports.
+
+ Those who wish can also use the synonym aggregator in place of master
+ in this command.
