Or, on the other hand, it may not close the leach.

All sails are not cut the same, all rigs do not respond the same.

Depends on the rig.

This will flatten the sail without closing the leech. To
depower you really need the leech to open and use a Cunningham to help
flatten.

The cunningham does nothing to flatten the sail. The cunningham pulls
draft forward.

Once again your advice is a worthless mish-mash of overgeneralization &
misinformation. It's kind of like insisting that you were in Boston, and
know all about it, when you were actually in Baltimore.
