This becomes quite confusing by the fact that even before the
first "--" the non-dashed arguments are interpreted as options
of xorriso's mkisofs emulation.
(I understand this from the interaction via ARGP_KEY_ARG
 between util/grub-mkrescue.c and grub-core/gnulib/argp-parse.c)

I would prefer to see a short mentioning that "--" has a special
meaning for the mkisofs emulation too, and that the first "--"
will not reach xorriso.


But again: Is this substantial change of user interface intentional ?

It makes the first "--" mandatory if any of xorriso's dashed
arguments shall be used. This demand is new and surprising.


Have a nice day :)
