I made a breakout board for the connector and it’s available on OSH Park here:

I also have 5 4 sets of the connectors (5 4 male + 5 4 female). If anyone wants a set, just send me a PM/DM for details for me to send it at just the cost of postage.
I was planning to make something like a thinkpad keyboard connector → framework keyboard connector, but I don’t have the time right now. It’d be interesting if anyone else would like to take a try at it though.
