Yes, we tried to include only the highest bang-for-buck keys in this set. It covers all of the layouts just mentioned, although sometimes there are compromises w/r/t legend, and less frequently, cap profile. Of course it would be best if we could please everyone, and include every single HHKB key, every 75% key, every 1800 key, multiple winkey types, blanks, scoop alternatives, extra B-profile bottom row keys, language packs...
.... and on and on and on.
Unfortunately every key adds to the expense, and the more obscure keys you add, the more it means you expect the average Joe buyer to subsidize everyone else's caps. Joe who buys the set for his Ducky or QFR isn't going to use any of those other caps and it's not fair to ask him to subsidize all those useless keys. Moreover, we have seen in other recent GBs what happens when sets get too big and expensive; they don't meet MOQ.
This set is not perfect, but no set can be perfect within the constraints of reality. You can't please everyone. We did the best we could to find the happy medium.
I would be willing to partially compromise and go back to blanks for the winkey if that is more agreeable for the majority. But there will be no additional keys added or other changes made. That discussion happened in the first half of the thread and it's done now. The choices made were sound then and they are sound now.
Now I'm working on sorting out the colors so we can get this up for sale and into everyone's hands as soon as possible. That is the priority now.
