One place where this seems to matter is to make sure the .rsrc section comes after .text. The Win32 UpdateResource() function can change the contents of .rsrc. It will move the sections that come after, but if .text gets moved, the entry point header will not get updated and the executable breaks. This was found by a test in Chromium.
