Not sure if that is correct, the logic currently is that its true by default, this would make it false by default, so only in the case of ignore: false we want to skip applying the delete patch

this is needed in cases where we want to populated controller applied default back into the virtual obj. i.e.
vObj.field1 = pObj.field1.
Currently the behavior of copyFromObject is like vObj.field1 = vObj.field2
But consider the scenario where
vobj
=====
spec.template.timeoutSeconds: nil (unset)
|

v
-------------------------------------------
pobj
spec.template.timeoutSeconds: 300 ----------> set by controller to default
I would want to (expect that) copyFromObject in reversePatches as defined
- op: copyFromObject
fromPath: spec.template.spec.timeoutSeconds
path: spec.template.spec.timeoutSeconds
conditions:
- empty: true
path: spec.template.spec.timeoutSeconds
would copy across physical <-> virtual boundary, but since both the args to ApplyPatches originated from same source obj, it was not happening

IMHO original name was confusing. So unless I understand the function incorrectly, the new name is much better.
Also add knative-serving plugin example
