Checkbox and Radio renderer, strict check

[michsk]

Is there any reason we have strict checks for single values and not strict for array values?

module-backend/Block/Widget/Grid/Column/Renderer/Radio.php::render()
line 78
if (is_array($values)) {
    $checked = in_array($value, $values) ? ' checked="checked"' : '';
} else {
    $checked = $value === $this->getColumn()->getValue() ? ' checked="checked"' : '';
}

The same is used for the Checkbox renderer. Maybe just keep it strinct and use in_array($value, $values, true) to be consistent?
