Fedora 40 (KDE) branched has it. Working great.

Current final release scheduled for 16th April.

So if you want to try it out. Get the branched Fedora release. Note: Currently pre-beta by about a week. At own risk.

Also some good stuff with AMD support and Wayland too.

Any time you want to leap on early the Fedora branched release is available and with update policy that will become beta and then stable Fedora 40 automatically.
