Eek. After that i would have to scrub my eyes with a wire brush.
But this question is already decided by the EFI capable ISOs of Debian,
Ubuntu, Archlinux, Fedora, and openSUSE. None of them has a partition
table entry. I am not aware of failure reports which point to this as
culprit.
Still open is the question whether mformat -k omits more preparations
which may be needed in some situations.

Meanwhile i found an example in grub-mkrescue.c about how to patch the
mformat result immediately after it was produced:
if (source_dirs[GRUB_INSTALL_PLATFORM_SPARC64_IEEE1275]
...
out = grub_util_fopen (sysarea_img, "wb");
if (!out)
grub_util_error (_("cannot open `%s': %s"), sysarea_img,
strerror (errno));
memset (buf, 0, 512);
fwrite (buf, 1, 512, out);
...
fclose (out);
With due adaptions this gesture could well zeroize the 64 byte of
partition table in mformat's (pseudo-)MBR.

Have a nice day :)
