No, it's not like that.
The trouble is that, with the GE KML, we had instantly the latest caches, even if I went to the PC in a cybercafe.
With your method, I would need to carry the latest GPX with me to anywhere I go in order to have the same funtionality.
Now, if you don't like/don't need/won't mess this (or another) funtionality, fine, good for you, I respect that.
But what you're doing is saying that everyone who cared for that are stubborn - or worse. If it's fine by you, that's nice. But you can't say anything helpful, then don't!
