Without meaning to prolong the discussion... NORDE is just not popular enough as per the numbers ran by every buy of the last x amount of time. It's a shame because I'm all for inclusion, I reside in an ISO country as well as I've stated elsewhere (though I use ANSI) but it's about cost/efficiency. You're not going to impose an extra $15 or 20 or however much is necessary to cover NORDE and such specific layouts, you cannot do that whilst being cost efficient. The cash things like a numpad pull in (and would pull out if removed) on the other hand is sizeable compared to Norwegian keys for example, if there's a choice to be made the choice will err on the side of the majority, so long as there has to be a choice you will not be able to sway that but with numbers.
You're in the minority if you're using any kind of ISO, that's indisputable, big part of it surely being that paying import tax/large shipping fees on things that come from outside of the EU - you can't change that, and so long as the minority is so minute it's not going to happen. No one would oppose to it if the costs were $0, no one's against helping others I would assume (or hope), but they are not.
I wonder what is the price of the 1.5-1-1.5-7-1.5-1-1.5 bottom row? From the granite R4 analysis it seems that it is about as popular as norde-uk would be.
It's my assumption, from my time being here and other keyboard forums, that Winkeyless is more popular than any ISO kit; you have people in ISO using 7u space bars, as well as all over the rest of the world. You have to remember that Granite was in its fourth run at the time, so it may be that people already picked up the main kits in earlier rounds. I remember the thread for Granite in its latest round and there were many who were joining simply to pick up any odd child packs they didn't already obtain in earlier rounds.
GMK sets cannot be compared easily to how SP sets are broken and run. GMK standard main packs are very similar to what's being done in this IC--not much more, not much less.
I'm well aware of what previous gmk sets have comprised of. I would not be voicing my opinion if I did not want a slight change to it.
There are also european people living across the world, same as winkeyless users. Also, why the sudden interest in winkeyless ISO users? You did not seem to have any before. I dare to say that if an opportunity, first ever, to buy an international gmk set presents itself, I don't think that a small issue like 1,5U mods are going to make one not buy the set.
As far as I know the fourth granite run was the largest one yet, and if people were, as you suggest, mainly picking extras, would it not show as an additional interest in, say, winkeyless layout? By your argument the popularity of winkeyless layout would be even lower than 8% in a typical buy.
If SP kit popularity/structure cannot be used to determine the need for certain keys, how can you at the same time use them to say that international keys are a small minority?
