I guess they figure there is not enough of those to worry about. I have seen several however.

I am glad they didn't grandfather locationless and they they removed them all from the site.
I am glad they did grandfather virtuals so the existing ones could stay. I wish they just still allowed new ones gc.com!

I totally dislike that on one of my caches they grandfathered virtual stages of a multi as being able to be treated as a physical stages and then turned around and went back on their word and took it away from me. But I guess some days ya just gotta go with the flow. In the end I guess they are doing what makes sense to them, even if we would do it differently.
