If anything, the changes required for the GUI work will make scripting

Essentially, the GUI works by executing GRASS commands. In order to
work effectively, the GRASS commands need to be able to operate
without any user interaction. No yes/no prompts, or waiting for the
user to do something with the mouse, or expecting data to be entered
via the terminal.

Any changes which make a program more useful to the GUI should equally
make it more useful for scripting.
