Refund process of a marketing package to return the associated products into inventory

Here is a duplicate of a comment I made at OFBIZ-12392:

I expected the refund process of a marketing package to return the associated products into inventory instead of the marketing package product as I mentionned there: https://markmail.org/message/s7bbwn5fj5xnezon

But reading back this thread, and rememoring the situation, I think I then confused Opentaps and OFBiz. Because as explained by David, and noted elsewhere by myself, OFBiz is not able to do that, when Opentaps was.
