The same happened to me with some other caches.
There is no way to discuss every cache in that list in the comments to this post. There should have been comments directly in the Moderate tab for every cache and a way to reason your votes. Also the description "what is a challenge" is really not clear from that description on that page. Not even for me, but how for the tens new guys who joined in last week?
Should a challenge be something that (can) have a challenge checker? In that case, both of your pointed out challenges should be in this list (if the cache is bonus, it should not have listed coordinates). Or is a challenge something that you need to do something, such as GC3DD4E or GCVWRE which would not qualify based on the new rules and can not be verified by a checker?
For your challenges, I would say both of them are challenges, even though they are pretty simple without any invention. But what about these two I mentioned above?
