That goes right along with my own personal opinion. I only ever use O or X ringed chains which should be permanently lubricated from within. I absolutely hate oil fling getting all over the rear spokes, wheel and any other parts and I am not real concerned with a light surface rust. I use Dawn dish detergent and warm water to clean my chains followed by a low pressure water rinse and allow it to dry. What I noticed with any and all external lubricants I ever used is they all attract dust and dirt and give it a sticky place to cling to. On the other hand if I leave the chain dry with no lube at all and go for a dusty ride I don't have much dirt or dust clinging to my chain or sprockets. I use regular motor oil at the end of the riding season and wipe the chain down with a moistened rag for winter storage just to prevent too much rust from forming.
I just installed 2 new DID X ring chains on my BW 350. From the manufacture the internal grease appears to be a white lithium formulation but the outside external lubricant is more like a wax. I bet this external lube is simply used for the purpose of rust prevention while the chain is in it's box. It would not be great to open a brand new ringed chain only to find a light coat of rust forming before it ever was on your bike. As always, you can use what ever you like on your bike and chain and nothing I do is meant to be advice. I hate trying to clean spokes and rims after they have sat with years of chain lube slung all over them and all the dirt, grease and grime that sticks to it.
