If this is considered I would beg for addind an option to keep autosave work for those who have different approach. If you keep the paradigm one project = one separate directory there shall be no problem with autosaving as you have only one Rdata file together with exported pictures, pdfs, xls and doc files. If you save history to separate files you can also easily keep track of your work. If autosave is disabled and you could leave your session without warning I bet that there would be hundereds of questions similar to: I worked whole day and after quitting R all my work is lost.
