I do apologise if that's the case it's not something I've ever seen written. Have you got a link to the shimano document ?
Please don't apologise.
Some people are very obsessive about how they lube their chain. Like most people, I have a little routine that seems to work for me and you will have one of your own I'm sure.
I like to think I'm somewhere in between, I wouldn't run it dry until it siezes but I also don't buy expensive bike specific oil either (except last weekend just because it was £2.00).
If you remove the factory stuff, as long as you lube it afterwards it will be just fine. It's just that there's no need and it stays on for a good few months with my riding. And that's all you'd be losing out on really, no harm will be done.
Mechanically, a chain is a low tech device and in my view doesn't warrant such in-depth attention other than routine cleaning and a drop of oil...any oil.
Today's oils are highly synthesised to achieve certain properties. A chain oil only has to be thin enough to penetrate and it will work. The rest of the properties are just nice to have ie. repel grime, stay clean, stay on the chain etc. which many people see as a worthwhile benefit.
Having said that, my bike is a very old, cheap and cheerful hybrid so it's not as if I'm at the cutting edge of bike technology! Also, my typical cruising speed is between 15 and 18 mph so not as fast as a racing bike which might or might not have an influence on oil choice
Anyway, here's a link I found for you as requested.
