Magento 2.4.4 API PUT products

question of interest.

We are using the PUT command for updating our products, but the data in custom attributes are not cleared when not sending in the body:
rest/store_view/V1/products/sku

Is that expected behavior from Magento? We expect that a POST or PATCH is updating only the selected attributes and that a PUT would clear all attributes which are not sent in the PUT request.
