One does (it's a southpaw, numeric keypad on the left). A few are TKL (full size keyboard without the numpad).
Actually, as a programmer, I pretty much never use the numeric keypad. But when I start seeing smaller layouts with no arrow keys, Fn keys, or even number keys, I tend to agree: there's a definite trade off between function and aesthetics. The beauty of custom keyboards is people get to decide those trade-off's themselves.
As a dev I also have very little use for a numpad. Unless it’s a the weekend and I’m messing around in Blender, it along with the traditional home/end cluster and arrows are just a bunch of dead space pushing my mouse way too far the right. I much prefer the numpad being it’s own separate thing that can be moved around, but a southpaw setup would be ok too.
The worst thing is when laptops come with numpads, pushing the trackpad off to the left and making it impossible to center my arms while typing. Drives me crazy.
