Weapon/Armor Enchantment (but not Staff) is subject to Remove Thrown Spell, but I wouldn't consider this to a useful tactical option.

Control gate needs the Creation Spell range restriction because otherwise you get two different range rules for stabilize gate. If asked tell the players they are "creating" a new rule set for the gate.

My question is what would happen if you cast Remove Thrown Spell on Duplicate or Delete Writing targets?
