Work on Single Node OpenShift is ongoing; currently it can be installed on AWS by adjusting the install-config.yaml to have only one controlPlane node (which then needs to be specified to be at least m6g.2xlarge or larger) and zero worker nodes.
As for the RasPi, only RHEL-compatible machines will be considered for OpenShift enablement, and RHEL for ARM requires ServerReady SR compliance along with device driver support in the upstream kernel. (For more information, see https://access.redhat.com/solutions/6673691.) The RasPi fulfills neither condition. Furthermore, while 8 GB memory is usually sufficient for a minimal worker node, it is generally insufficient for a control plane node, particularly in a 3NO or SNO configuration.
However, you may want to try MicroShift as an alternative; https://next.redhat.com/2022/01/19/introducing-microshift/ mentions the RasPi4 as a possible target. Please note that MicroShift is not officially supported, so please do not raise issues here about it.
I hope you find this information helpful.

Well isn't it an ongoing issue? Or are you tracking elsewhere as well?

The 4.9 developer preview is only targeting AWS, and you can try SNO on AWS right now as described above. Other platforms are out of scope for this issue tracker.

Side note: Using this firmware for the RPi, one can actually make it sufficiently SBBR-compliant for deployment of Fedora CoreOS (and probably RHEL CoreOS too): https://github.com/pftf/RPi4
Obviously that requires the creation of a custom boot image.
And there's still the issue of insufficient memory for OpenShift masters.
