Should Creatable be mutating its options prop?

[ericchernuka]

Mostly a question on the rationale for Creatable mutating the options prop when a new tag is added, but a onNewOptionClick is not defined. Currently on the examples site the options from state are directly mutated which seems like a bad idea.

The code below from Creatable (https://github.com/JedWatson/react-select/blob/master/src/Creatable.js#L95) shows the mutation:

if (isOptionUnique) {
	if (onNewOptionClick) {
		onNewOptionClick(option);
	} else {
		options.unshift(option);

		this.select.selectValue(option);
	}
}

Was this intentional or was it for those using things like MobX?
