	// OperationReplace substitutes the referenced dependency with the middlewares of a modification.
	// If replaced with an empty modification, this acts like a deletion
	OperationReplace

	// OperationAppend adds the middlewares right after the referenced dependency
	OperationAppend

	// OperationReplaceAllUnsafe replaces all middlewares in a chain with those in the modification
