Why schema is not rendered when properties.length is 0

[MGouaillier4CT]

As i use ASF in my project, i sometimes wish to render forms that don't have any properties. I was wondering why my form was never rendered and i came across this condition :

if (form && schema && schema.type && 
    (lastDigest.form !== form || lastDigest.schema !== schema) && 
    Object.keys(schema.properties).length > 0) {
        lastDigest.schema = schema;
        lastDigest.form = form;

        render(schema, form);
}

Is there a particular reason why a form need at least one property ?

@MGouaillier That's the schema property object and no it doesn't.

It shouldn't be required in the alphas already, it has been commented out in the code and I will most likely remove it once I finish the bit below it.
