A small thing about OS support.
Do you intend to backport this for older versions? That would probably make sense, with adjustments for supported versions.

RHEL 8 is being removed for 3.23+. If you use this table for earlier versions, I suggest you include the (default) marker for iptables for RHEL 8, for consitency.

Additional information:
Adds a note on the supported data planes for non-cluster hosts.
We never explicitly called out the data plane supported by non cluster hosts, and https://github.com/tigera/calico-private/pull/12294 now sets up the packages to handle it properly.
