productVariantsBulkUpdate has replaced the deprecated productVariantUpdate for single variant updates in 2024-10
However productVariantsBulkUpdate is missing requiresComponents from the allowed input fields:
productVariantsBulkUpdate - missing requiresComponents
productVariantUpdate - allows requiresComponents
Somewhat understandable as previously there wouldn’t have been a strong need to add requiresComponents in a variant bulk update - but now that bulk update is the preferred approach for single variant updates, this value should be available.
