 # @SocketAddressLegacy:
 #
 # Captures the address of a socket, which could also be a named file descriptor
 #
 # Note: This type is deprecated in favor of SocketAddress.  The
 #       difference between SocketAddressLegacy and SocketAddress is that the
-#       latter is a flat union rather than a simple union. Flat is nicer
-#       because it avoids nesting on the wire, i.e. that form has fewer {}.
-
+#       latter is has fewer {} on the wire.
