I’m not a Framework employee, but I would refer you to the Framework knowledgebase article on the topic. Officially Supported vs Compatible Community Supported Linux Distributions
The Framework Linux Support team is quite small (currently a total of 2 people). They’re focusing on Ubuntu and Fedora for officially supported distros because they need to keep that list small enough that they can constantly evaluate it.
Even the community supported list is unlikely imo. For one thing, while I don’t have specific information on it, I would think a fully-functional touchpad would be a requirement as it makes a huge difference to the user experience. Also, even for the community-supported distros on that list, Framework maintains install guides (updated periodically) and occasionally tests to ensure functionality, which is time consuming and likely not worth it for such a niche OS.
If you’re interested in showing the OS’s compatibility and making it easy for people to use Sculpt OS, I encourage you to create a guide thread here on the forums, like the ones that the community has made for OpenSUSE, Debian, Nix and Arch
