I tried to look these up. 802.3cg seems to specify 10BASE-T1S and -T1L. T1S is short range and multidrop. T1L is longer range but point-to-point. 802.3bw is 100BASE-T1 and is (I think) point-to-point. 802.3da seems to be working on enhancements to the cg spec. It seems reasonable to me to have three standards here. They support rather different use cases. Also, 100BASE-T1 seems to be getting a bit less traction — for automotive and industrial uses, 10Mbps seems like more than enough, and improved reliability on less fancy cable seems like a win. The BeaglePlay is 10BASE-T1L, which seems like a fine choice to me. -T1S is a bit short range to use for a house-wide network depending on the size of a house and how straight the wires are. Of course, for -T1L to be of much use, we need cheap switches, preferably powered with PoDL. edit: a better end game would be for all the gadgets to have internal switches and at least two ports.
