802.3, cause 32.1.2, 2015 version:

   A 100BASE-T2 PHY can be configured either as a master PHY or as a
   slave PHY. The master-slave relationship between two stations
   sharing a link segment is established during Auto-Negotiation (see
   Clause 28, 32.5, Annex 28C, and 32.5.2). The master PHY uses an
   external clock to determine the timing of transmitter and receiver
   operations. The slave PHY recovers the clock from the received
   signal and uses it to determine the timing of transmitter
   operations, i.e., it performs loop timing, as illustrated in Figure
   32–2.

In this case, i would say master/slave is very clearly defined.

Given these definitions, would you like to propose alternatives?

Do you have any insights has to how the IEEE 802.3 standard will be
changed?
