Change page format for ODF 1.4 onwards from US Letter to A4

A4 format is required for submission to ISO. ODF 1.3 was submitted with modified margins to preserve line and page ends. ODF 1.4 and onwards should be published in A4 format by OASIS, so the margins should be restored to their original values. Should this margin reset be done for ODF 1.4 (already at Committee Specification stage) or only for ODF 1.5?
