That thread does seem to back up @gotmax23 's point:
Discussions about Hummingbird inclusion in the Fedora Project are in the
early stages, but there is no such thing as Fedora Hummingbird. IMHO,
this post should be taken down and reevaluated, as it sounds like there
was a miscommunication about Red Hat’s Hummingbird Project being a
Fedora deliverable.
It shows IBMRH employees enthusiastic about pushing this forward, but it’s not clear that this has gone through the steps that would make the “Fedora Hummingbird” branding appropriate.
It’s said in the thread that:
The initial goal would be to bring the work into Fedora by creating a Forge account and SIG, while nurturing it under the Fedora Innovation Lifecycle proposal
…but the Fedora Innovation Lifecycle itself is not yet approved and further work on it has been requested by the Council.
