Another update: forget about it, this doesn't work anymore in Windows 10 which seems to have become more strict about partitioning and treats all variations on the new ISO format as unknown. Curiously though, it happily mounts the partitions in explorer, including the EFI partition, but the partitioning tool just says no. Since most of the people writing the sticks will be using Windows, I guess we'll have to give up on the idea of adding a writable partition to the installer medium and just require a separate stick.
