Erm, not really.. Lets just keep it simple shall we?
And not EVERYONE likes to use an adv. train, I myself absolutely LOVE the whale. Only 300 less cargo space than an adv. train, and is much smaller and slimmer, perfect for asteroid fields.
plus, if you multiply 5000 cargo space by 1.2, it's only 1000 extra, so what's the big deal?
If you think 5000 cargo is too much, then that is 100% fine with me. Use something like a normal train, or a luxary liner..
What you think is your's and your's alone, but most people kind of like the Cargo space enhancement idea, despite the fact that it might not be possible..
Another recap: 1.2 cargo space multiplication, 50% armor reduction.
