Is it though? TB has native support for DisplayPort streams, but the article doesn't reference DisplayPort at all, and does make several other references:

> A decade ago, Intel showed off something very similar: a 10Gbit Ethernet-over-Thunderbolt demonstration called Thunderbolt Networking. This is a faster version, an Intel representative said via email. Thunderbolt Share uses up to a 20Gbps connection over Thunderbolt 4 with low latency

> Essentially, you’re performing a local, cabled version of Microsoft’s Remote Desktop without all of the setup.

I don't think there's any reason yet to believe that this isn't just a proprietary (or possibly even just embedded VNC) screen sharing solution that's tweaked for a high-bandwidth low latency connection.

macOS has a "high performance mode" for its regular screen sharing (as of v14, Sonoma) which works amazingly well even over wired Gigabit ethernet.
