The comment was previously suggesting the returned value is similar to the one stored in $_FILES, while it is more similar to the way PHP stores submitted form values. It is actually more convenient to have it this way, so rather then changing the returned value (which would break BC), it is better to clarify the comment.
HTML allow to define different form fields with the same name.
Imagine the following form:
<html>
<body>
<form action="/">
<input type="hidden" name="option" value="default">
<input type="radio" name="option" value="A">
<input type="radio" name="option" value="B">
<input type="hidden" name="settings[1]" value="0">
<input type="checkbox" name="settings[1]" value="1" id="setting-1">
<button>klickme</button>
</form>
</body>
</html>
Since the `FormFieldRegistry` can only handle one field per name, the
hidden field option is registered first before the radio field with
the same name is evaluated. Thus, the `FormFieldRegistry` returns an
`InputFormField` instance on which the `addChoices()` method can not
be called.
If you have a select with attribute name="foo[]", and you submit your form, http_build_query returns empty string as a result. In this case you get a form extra field validation error, because your field "foo" converts to
'' => bool(false)
This PR was squashed before being merged into the 2.3 branch (closes#8197).

* domcrawler-disabled-fields:
[DomCrawler] fixed disabled fields in forms (they are available in the DOM, but their values are not submitted -- whereas before, they were simply removed from the DOM)
$node->hasAttribute('disabled') sf2 should not create disagreement between implementation and practice for a crawler. If sahi real browser can find an element that is disabled, then sf2 should too. https://github.com/Behat/Mink/pull/58#issuecomment-1712459
