Re:Show HN: Searchable Kubernetes CSI provider listing

Disclaimer: My full time job involves developing a CSI driver that is on this list (not simplyblock, but I won't say more than that to avoid completely doxxing myself).
A lot of this chart seems weird - is it somehow autogenerated?
For example, what does it mean for a driver to support ReadWriteOncePod? On Kubernetes, all drivers "automatically" support RWOP if they support normal ReadWriteOnce. I then thought maybe it meant the driver supported the SINGLE_NODE_SINGLE_WRITER CSI Capability (which basically lets a CSI driver differentiate RWO vs RWOP and treat the second specially) - but AliCloud disk supports RWOP on this chart despite not doing that (https://github.com/search?q=repo%3Akubernetes-sigs%2Falibaba...).

I bet there are lots of mistakes yet. It's a slightly extended list of the csi docs for now. The features mentioned are the features that the docs mention.

Another example, what does it mean for a driver to support "Topology" on this chart? The EBS driver allegedly doesn't despite using most (all?) of the CSI topology features: https://github.com/kubernetes-sigs/aws-ebs-csi-driver/blob/7...
Also, listing "ephemeral volume" support is kinda misleading because Kubernetes has a "generic ephemeral volumes" feature that lets you use any CSI driver (https://kubernetes.io/docs/concepts/storage/ephemeral-volume...).
