However, even though Virtuals and Webcams have been grandfathered, they are still abundant in most places. True, you might not have one in your home zone, but it should be possible to find such a cache with reasonable effort (i.e. some travel might be involved, but it won't be half way around the world).
I would vote for leaving these two types in for the time being.

I've just checked and find I have 8 virtuals and a webcam cache within 45 miles of my home.
