Note the various amounts of space within the rope luff grooves.

None of those sections has sufficient room for the luff rope to flake down
on itself, which was your original suggestion. Moreover all of them have a
solid wall backing up the groove. This is essential for strength reasons
and
to stop the groove gaping open when the mast bends


Then by what you have said, is it impossible to reef a rope luff sail?
