Bazzite doesn't have the new "Anaconda Web UI Installer"

Bazzite’s download page states the iso is now based on Fedora 42, correct?
But when I try to install it, it’s still using the old installer.
Any idea why?

Because the new webui installer is only available on Fedora Workstation, nothing else

Universal Blue as a whole is moving to FyraLabs Readymade instead:
