This had been left out unintentionally earlier. Because theoretically there might now be existing objects with parameters that are larger than whatever limit gets enforced now, the limit only gets checked when parameters get created or modified. This is similar to the validation of CEL expressions and for consistency, the same 10 Ki limit as for those is chosen. Because the limit is not enforced for stored parameters, it can be increased in the future, with the caveat that users who need larger parameters then depend on the newer Kubernetes release with a higher limit. Lowering the limit is harder because creating deployments that worked in older Kubernetes will not work anymore with newer Kubernetes.
