Is your feature request related to a problem? Please describe.
Currently, observedGeneration is only set in status level for al resource. It would be helpful to set observedGeneration under conditions as well. To reliably rely on kubectl wait command for ready condition to be met.

If the previous condition was ready for HR resource then, sometime kubectl wait will confirm to soon as condition met based on previous Ready condition.

Describe the solution you'd like
observedGeneration should be set under condition.

Describe alternatives you've considered
We have are sleeping for 30 secs hoping the status will be updated in the mean time.
