it's not always that straight forward to connect xdebug to where you need it, especially if that is triggered by some API call from external uncontrolled system. if that error could just trigger some generic error like product/entry/item is invalid so you would have no idea with exact condition failed. finally there in e-commerce offer there are import processes that get thousands of products in single batch, logging will get very messy and getting to that one product that had issue might take some time in each run we had some errors that were happening to only one client and noone could reproduce that.
