1.16 deployment doesn't work on older clusters

[pohly]

I think that means we should remove any CI jobs that test newer deployments against older versions.

Agreed. Those jobs would have been useful if a) they worked (obviously... 😁 ) and b) if we wanted to support running newer sidecars on older Kubernetes releases. With the interpretation of "recommended Kubernetes version" as "this is what we released for, don't run on anything older even if it would work", we no longer do the latter.

will this mean actually dropping support for older versions, or just for the deployment?
if I use a custom deployment can I support older kubernetes versions?

Our 1.16 version of the deployment specs uses a new api field introduced in 1.16.

So if you want to deploy on an older cluster, the deployment spec should not use the new field (and therefore not support the new 1.16 functionality)
