Something like the Kumo?
This list is missing a bunch of new boards coming out, too. @jackhumbert is offering hotswap on Planck Rev6 and I think is planning on using it on his future boards. @evangs is using it on the Kumo at least, and I think future minivan revisions will have it as well. I think the new Rama board is using them, too. The popularity is certainly growing!
I still prefer to solder my boards, personally, just because I like the feel of assembling it all myself, and popping switches into sockets just isn’t as satisfying. I certainly see the appeal though, and will own a few soon enough. I think it is a great thing for pulling more beginners into the customization side of the hobby. Not everyone has the sort of background that makes picking up a soldering kit easy, and that is ok. I definitely appreciate the ingenuity that people are showing in getting hot swap pcbs to support multiple layouts, though I would potentially like to see that extend even further for a more “enthusiast” audience. I can’t speak for anyone else, but I at least would be willing to solder my own sockets on if that is what it takes for some of the more niche layout support.
The only real worry that I have for the future of hot-swap is it killing off some of the less frequently used layout options or needing to commit to a single layout when you pick your pcb out. I don’t think we are even close to that becoming a serious concern though.
