@DarthSim @dragonsmith can somebody pls take a look here?

Hey @kaufmo! I don't think that's a good idea. This change will break things for all our Pro users and those who deploy imgproxy from some custom repos.

Unfortunately, this change will break backward compatibility. I guess, you can configure renovatebot to look for the image.repo key in the imgproxy values. Bot's helm-values manager should have this feature, if I am not mistaken.

On the other hand, repository is the standard key name. Let me close this for now since even if we decide to change this, it would involve introducing an alias, helper, deprecation warning, etc. I'll circle back to this issue later today.
