The frustrating thing is all the information and materials to support Samsung devices is out there, but the custom ROM development community is so ridiculously toxic and unhelpful to newcomers that few people are willing and able to mainline new devices (and supporting a new device is complicated enough that you pretty much can’t get started without someone more experienced to point out the decades of cruft, pitfalls, and vendor-specific workarounds that the build processes have accumulated). More of the old guard leaves every year without enough new blood to replace them.
