What is SpaceFN and why you should give it a try
The SpaceFN concept - setting up your space key as a layer switch when held - is probably one of the most useful tweaks in the keyboard hobby. Let me explain how it works. My SpaceFN article on kbd.news made some rounds recently - quite surprisingly given the age of this concept. This piece you're reading is a condensed version of the full post. If you're left with unanswered questions, you'll most likely find the info you're looking for in the original write-up. On my imaginary top list of the most useful keyboard features, tweaks and hacks, SpaceFN would deserve a podium finish for sure. But what makes it so special? In short: SpaceFN is easy to implement, easy to learn, costs nothing, can be used with any keyboard, and can improve your productivity instantly. I will list its benefits below, but can state right at this point that the SpaceFN concept, setting up your space key as a layer switch when held, is clearly one of the most useful tweaks in the keyboard hobby....

There is no 1.75 R2 key, and no 1.25 R3 key, so my 40% keyboard can't use these (the 1.75 R2 key is used by Minivan keyboards, and the 1.25 R3 key is used by the majority of 40% keyboard layouts).
Also, my 60% Ortholinear keyboard cannot use these (basically a Planck layout, with F1-F12 keys above, and a Numberpad to the side). The missing R3 Tab key is a minor inconvenience, but the biggest problem is that I have to spend $46 on the normal "Mods" pack just to get the F5-F8 keys.
I totally understand the predicament of having to support a limited number of keyboards, due to having a limited number of molds. However, just 3 points I'd like to try to make:
- You are missing support for nearly every single staggered 40% keyboard layout by omitting about 1-2 keys. - The F5-F8 keys should be included in the Base pack. Not only are there keyboards that use F1-F12 keys, but do not use standard modifiers. Also for aesthetic reasons. Not everyone likes the 2-tone look. - Symbol modifiers would solve alot of other support problems. Some people are totally turned away when they can't find correctly labelled keycaps.
My thinking is that I don't need 2 sets of number keys on such a small keyboard. However, I do have macro to switch the F1-F12 keys to swap them for a traditional number row. I figured I'd do that for gaming.
Also, you mentioned the sculpture of the R0 vs R1, for me I actually prefer that the sculpture is "off". because it makes it harder to accidentally press an F-key. I'm currently using Cherry profile keycaps on this keyboard, and the F-keys are just tall enough to remind me that they are the wrong keys when I reach for a number key.
If I was buying a set like this, I would prefer that the sculpture be correct (if I can be so picky), simply for aesthetic reasons.
