I noticed today that Rancher 2.6.5 was released (https://forums.rancher.com/t/rancher-release-v2-6-5/37891/3) and in it RKE2 deployment goes from tech preview to general availability, but that's only with Kubernetes v1.22+.
Can any Rancher folks let me know if there're plans to extend that to earlier Kubernetes versions? We've got a reason that we were hoping to use v1.20 at the moment, so I'm wondering if my best answer is wait or push a completely separate team to upgrading Kubernetes versions.

No, 1.20 is end of support. 1.21 is at most one patch release from end of support now that 1.24 is out.
Was not worth backporting the necessary fixes to take 1.21 GA when it was like a week or two from being end of support.
Note that these versions are for the clusters that are provisioned by rancher, not the versions that rancher is running on. Rancher can be running on 1.20 or 1.21 and provision downstream clusters on 1.22 or 1.23

That's what I was afraid of, but thanks for the confirmation.
