I believe it was better when the authors and the entry numbers of the eliminated designs were shown.
For example in contests with many eliminated entries when I want to report someone for copying I check all his entries to see if he had same idea before me, that was previously eliminated (I don't check eliminated designs when I submit) and then he made a version of his design after me - this is not a copy. Or he made several designs copying me and some of them were eliminated - this is a copy.
It's very hard to tell the difference if you cannot track the entry numbers of the designer's eliminated entries
