Any more update needed from me on this one?

Friendly reminder. Thanks!

Could you use helm template to show if all the fields set right?

[killerwhile]

Yes, just helm templates . from the helm/tenant folder.
Defaults were already present but commented out in kes object, and my PR is only using the attributes that were already present but not used from kes object, defaulting to the old behavior for backward compatibility.
