No, because I never consider attempts to delete a non-existent item as
an error and thus would always suppress the error message.
But still return 404 to the engine, I assume.
After all, the desired outcome was achieved.
This is different for reading where not getting the item data may or may
not be relevant.
Yes, seen from a standpoint where the result of the operation counts, and not the process,
a failing read is relevant while a failing delete is not - the desired result for the
latter (item gone) is ok, even if the item has disappeared sometime before.
Makes all perfect sense to me now :-)
