@atoato88 thanks for looking into this!

@justinsb Gentle ping: Can you take a look at this when you get the chance? This impacts us as well.

Thanks for fixing @atoato88 ... this was an unfortunate change in a library that was supposed to simplify things :-( With server-side-apply, I'm not sure how much it is helping us. We also have https://github.com/kubernetes/kops/pull/13753/files in another project (kOps) which could be a better applier, and our appliers are now pluggable.

In any case, thanks for this and sorry about the delay!
