I think Russell and Andrew did a good job clarifying some quirks with all these standards :
https://elixir.bootlin.com/linux/latest/source/Documentation/networking/phy.rst#L229
There are some more info in Andrew's LPC talk here : http://vger.kernel.org/lpc_net2018_talks/phylink-and-sfp-slides.pdf
(more phylink related though)
But I agree that this is hard to fully grasp, there are so many variants everywhere, some standard, some ad-hoc standards, etc.
Maxime
