As someone not into the hobby (although I have a cookie cutter mechanical keyboard), what is the point of having that few keys? Portability? Otherwise i find it more cumbersome than efficient having to constantly use modifiers to access the full range of keys I might want to press.

As a user of a small TKL keyboard, I can say from my own experience having a small keyboard makes it easy and less strenuous to switch between the mouse and keyboard since they are so close together. I also find I don't really miss the extra keys, I can do my job just fine if not better without them, because of the added benefit of moving fast.
I currently do a data heavy job and almost never use my keypad. Just can't come to terms with letting it go. 96% might be the step that gets me to ditch the numpad!
I use my keypad a lot for my job so I’ve always been kind of jealous of the people who can use the slimmed down keyboards. This is a cute little compromise and I’m glad to know it exists!
To me the main advantage of having less physical keys but a full layout available via modifiers is, that your hands won't have to leave the home-row. Working like this is not only much more comfortable but also a lot more efficient. (At least for me)
