Developers are more likely to use software that's designed for multiple platforms, without priority given to the Mac. (I guess if you assume not all developers live their life in Xcode.)
This means that developers are more likely to be regularly using software that actually depends on the keys they stripped off to make the touchbar, and/or software with sub-par to nonexistent touchbar support.
Most developers I know use rarely touch the laptop keyboard. On my desk I have a bunch of monitors and an awesome mechanical keyboard. The only time I need the built-in keyboard is when I'm away from my desk.
