What should we add?

Currently, not every gate support label argument definition. For example, the x gate does, the i gate doesn't. Is there a design reason for this? I tried to manually add the label argument like this:

    def id(self, qubit: QubitSpecifier, label: str | None = None) -> InstructionSet:  # pylint: disable=invalid-name
        """...
        """
        return self._append_standard_gate(StandardGate.IGate, [qubit], (), label=label)

But the custom label is still not displayed while drawing. How come?
