It depends on what program one uses for opening CSV i guess .. If the users are only going to use EXCEL, it makes sense to add an extra = in the exports .. if not, that's again an issue .. also, CSV format dictates that it should be "=""000123""" .. or just import it as .txt file and treat the column with leading zeroes as text ..
