Sikuli is also based on a similar idea and is written in Python. I am guessing it boils down to preference, but writing code as it is written now involves a lot less 'mouse' and much more keyboard, which most developers, me included, take for granted. I do agree that currently code written has very high limitations on re-usability, primarily because code is written with a specific project in mind. I believe two things can be done to make it more re-usable: 1) either have all developers write code with the idea in mind that they are writing independent libraries and not code for part of a bigger project so the code becomes much much more modular and decoupled and can be used in other projects on the fly. 2) create an extension which creates a project specific visual map for the code, which would in turn allow other developers to pick and choose code to their liking while having a greater understanding of how the code actually works. This being said, the author's efforts are much commendable.
