A bit OT here but I'd like Moodle to have an option within the Assignment settings to say whether you want PDF conversion for grading or not and allow the old grading method. This is a personal preference of the teacher, some like it, some don't. Some want to download and grade, some like to print and grade. Some use a projector in a classroom, some just the whiteboard.
Like we do with student's learning styles, we shouldn't shoehorn teachers into methods of teaching.
