I’m not really, just the only one with (incomplete!) open source designs.
I’ve recently focused on my main project again so haven’t worked on this further, but I have fixed some gripes with KiCad in regards to custom rules (which is basically a requirement for 6-layer boards), though there’s still one more bug to fix before it’s usable without going crazy.
So as soon as I find some extra time somewhere I will attempt to recreate my current 4-layer design as a 6-layer board which will be a lot better and easier to work with going forward, including 8i port instead of dual 4i port, USB hub, and potentially PCIe redriver/retimers.
Ofc I invite anyone that wants to do an open source version to do just that. I can share my 6-layer template and fixed KiCad build for anyone willing.
