> Either way, users are not expected to be mixing and matching single-pair ethernet devices Which is precisely what made other Ethernet so powerful and rapidly dominant. I'm not disagreeing with you, just saying it's a shame. Say I want to make an Ethernet-speaking sensor of some sort, the sort of thing that might be on CAN today. I now have to make multiple versions of it if I want to sell into all those markets, which I'm not likely to do in practice. Which means there will be fewer Ethernet options on the shelf in some of those markets, which means they'll remain CAN for longer. Which ultimately means Ethernet doesn't become as pervasive as it could if all those things worked together.

I now have to make multiple versions of it if I want to sell into all those markets, which I'm not likely to do in practice. If it's the sort of thing that might be on CAN today, you'd put it on 10Base-T1S and call it a day The higher speed varieties aren't even going to be used in the sorts of situations where you'd normally be plugging in random additional hardware. It's a point to point link within a specialized wiring harness, whatever is going on each end is generally going to be specific to that environment. It's moderately annoying from a tinkerer standpoint to have to use adapters, but I'm really having a hard time coming up with real world scenarios outside of development/testing where it'd be useful to be able to plug a 10Base-T1L device directly in to a 1000Base-T1 link for example, or vice versa. I guess I could see some utility in a dual mode device for the two 10mbit varieties that could either be on a shorter multidrop network or a long run point to point, but even there I feel like a lot of those use cases would be in building automation type infrastructure where at the end of most of those longer T1L runs you'd have a few devices and a bridge to T1S multidrop would make sense anyways.
