Unfortunately that is usually how it goes. For instance with the Honda Accord, in Japan it is rebadged as the Honda Inspire... And the Honda inspire has features, options, and standard equipment that would put most of our US spec Acuras to shame... So naturally it has many features, options, and standard equipment that our US spec Accord does not offer.
However, in America the US spec Accord comes in V6, 6mt, and coupe variants and in Japan the Inspire does not... So there are pros and cons on either end... I would imagine that the Qashqai does not offer the All-Around camera system that our US spec Rogues do, so in essence they would need those parking sensors to have any kind of comparable front parking assist. I personally think our All-Around camera system is better.
If it means anything, the only option that I like out of the ones you've posted is the sunshade... I think the bar on the front bumper is too blingy, out of place and doesn't really serve a purpose, and the parking sensors aren't really needed with the front camera...
But I realize your point is that they even have these options anyway and not whether they serve a purpose or not so my point is basically moot.
What people on the Accord forums have done in the past:
A) Taken an unrelated trip to the region and went to a Honda dealer, bought the part/parts, and either shipped it/them here or brought it/them back with them upon their return.
B) They knew someone over in the region and have had them buy and ship the part/parts over.
C) They found websites that dealt with USDM parts specifically for Asian spec Accords and Inspires that shipped to the US for pretty hefty shipping costs, but at least they shipped.
D) Found the parts on Ebay.
All of these could very well yield similar results for Qashqai/Rogue parts. You may be surprised how many OEM Japanese spec parts can be found on Ebay:
