I think what you're suggesting matches the media helper code, but I'd just be a bit worried that some other extensions (not necessarily core Joomla) might be using those fields that you're now hiding to hold configuration data which they use in that extension. And then they'd be able to configure that data only after setting Restrict Uploads (which an administrator might not want to do).

Do you think this is a valid concern?

That is a valid concern, however, I don't know for sure.

To configure, enable temporarily Restrict Uploads to display/edit these settings and disable when done.

@robbiejackson your concern makes sense. But I see it that way, when a 3rd party extension is using the settings then it should also use the core upload API.

Yes, I would agree with those points.

Why is Ignored Extensions not hidden?

Because Ignored Extensions setting is utilized outside and inside the Restrict Uploads setting.

		$ignored   = array_map('trim', explode(',', $params->get('ignore_extensions')));

		if ($filetype == '' || $filetype == false || (!in_array($filetype, $allowable) && !in_array($filetype, $ignored)))

		if ($params->get('restrict_uploads', 1))
		{
			elseif (!in_array($filetype, $ignored))
		}
