If this ever changes, then i advise to test a grub-mkrescue made ISO.
I assume that it has the best chances to get the attention of GRUB developers.

How are they related to the ISOs offered as e.g.
  http://dl.amnesia.boum.org/tails/stable/tails-amd64-3.3/tails-amd64-3.3.iso
?

Version 3.2 is not to see there, but i have an old 3.1 and now got the 3.3 ISO.
Both have no EFI boot equipment but only MBR code for BIOS which hops onto
program /isolinux/isolinux.bin in the ISO. Made by an older version of
Debian's live-build, as it seems.
There is one MBR partition of type 0x17.

I wonder what the creation processes do, which you mention.
Are the USB sticks still recognized as "ISO 9660" by (/usr/sbin/)file ?
Do they have a GPT or a MBR partition of type 0xef ?


Have a nice day :)
