Hi @jbertozzi,

Thank you for taking the time to create this PR. However, I need to decline it because spec.volumeClaimTemplates.metadata.labels field is inmutable and our plan is to remove support for persistence.labels at all given they're highly problematic and users usually introduce backwards incompatibilities by mistake.

You can find more information about this in this other thread

#22364

Thanks
