Any developments getting Thunderbolt Bridge connections to work?

I'm attempting to create a Thunderbolt Bridge connection between a MBP and a Hackintosh with a Z390 board that has native TB3 support. I've researched this but have yet to come across a proof of concept. The idea is to setup a 10-gig style connection between the 2 systems. I can get the Hackintosh to show up as "Thunderbolt Enabled PC" on the MBP but there's no option for a Thunderbolt Bridge Interface on the Hackintosh.
