IANAL, but I don't think there is any "clean room hole in licensing": licensing is downstream of copyright law, and clean-room reverse engineering, if done properly, results in products that do not infringe the copyright of the originating work to begin with, so the license therefore never applies to them.

The "Ship of Theseus" license you've linked to attempts to define for itself what constitutes a derivative work, but what is and is not a derivative work is determined by copyright law itself, and there's no concept of imposing licensing conditions on works that your copyright never extended to in the first place.

Simply put, if something isn't infringing your copyright under the criteria established by the law, then your permission was never needed to do it in the first place, so the conditions under which you would or would not be willing offer that permission are irrelevant.
