As discussed in the corresponding issue, it should allow to easily distinct autocomplete fields from non autocomplete fields with a variable added to the view.

Before, I used to write this:

{% block choice_widget %}
    {% set attr = attr|merge({'class': 'my-input-css-class'}) %}

    {# Condition simplified, let's assume the stimulus controller can only be autocomplete for the example #}
    {% if attr['data-controller'] is not defined %}
    <select name="{{ full_name }}" {{ block('widget_attributes') }}>
        {% for choice in choices %}
            <option value="{{ choice.value }}" {% if choice.value == value %}selected{% endif %}>{{ choice.label }}</option>
        {% endfor %}
    </select>
    {% else %}
        {{ parent() }}
    {% endif %}
{% endblock %}

With this, it should be able to become as below:

{% block choice_widget %}
    {% set attr = attr|merge({'class': 'my-input-css-class'}) %}

    {% if not autocomplete %}
    <select name="{{ full_name }}" {{ block('widget_attributes') }}>
        {% for choice in choices %}
            <option value="{{ choice.value }}" {% if choice.value == value %}selected{% endif %}>{{ choice.label }}</option>
        {% endfor %}
    </select>
    {% else %}
        {{ parent() }}
    {% endif %}
{% endblock %}
