It seems there are many other examples on that page that could also be updated similarly. Did you single this one out for any reason? I don't know that it's really necessary, but I don't have a great argument against it besides it will be a bit repetitive in all the examples, especially if the implementation is something like {% if field.help_text %}<p>{{ field.help_text }}</p>{% endif %}
so we don't output empty paragraph elements.
I removed the "In addition, but unrelated" issue from the description as I don't think there's a need to complicate the example with a particular HTML structure. ("{{ field.errors }}
might need a span for the example to be usable in real life.") {{ field.errors }}
already includes a <ul>
which can be styled, correct?
