We noticed it is only possible to pass an ArrayExpression as twig component attributes.
This is not convenient of you want to e.g. merge 2 arrays in twig.

Example Use-case: if you want to create a custom form template that consists out of twig components, it is not possible to merge the form attributes into the attributes of your twig component.

{%- block button_widget -%}
    {% component 'atoms:button' with attrs|merge({theme: 'primary'}) %}
        {% block children %}
            {{ label }}
        {% endblock children %}
    
    {% endcomponent %}
{%- endblock button_widget -%}
