Like most others in this thread, I'm having trouble understanding what this is. Fedora Silverblue with dev-related pre-installed stuff? (rhetorical question)
Their presentation feels like NixOS. You open their webpage and the entire thing is unclear. If even the target audience doesn't get it, they probably won't use it out of their own volition or without hand-holding.
Dunno if there are Fedora maintainers on the fediverse or reading this thread, but IMO they should tell their BlueFin team to fix the marketing. Most people don't get what they're trying to sell.
