All cutters must have running backstays?

If you want to keep your mast in column under all conditions of wind
and seas, while flying an inner jib, that is probably true. You might
be able to get away with fore and aft lower shrouds on some boats.

You also have to consider the changing dynamics of a reefed main,
since the mainsail itself provides considerable aftward mast support.

If in doubt, talk to a good spar maker or rigger - it all comes down
to engineering.
