As someone who works for games, I think the biggest problem of node-based systems is... they're all different (in terms of UI/UX). Unreal blueprints, Substance Designer, Houdini, Blender's geometry node, Unity shader nodes... they all look different and act differently. Different shortcuts and gestures. Different window/panel management. Different programming languages have different syntax rules and libraries, of course. But at least they're all manipulated with one single interface, which is your editor. If you use vim binding, you don't need to worry about "what pressing K does". It moves the cursor down for all the languages. People who spent X hours customizing their vim/emacs will benefit from them no matter what language they use next. I spent a lot of time customizing my Houdini keybindings and scripts, and this effort will be thrown out the window if I later switch to Blender.
