 > Picture a third party looking into adding headers that your plugin adds,
 without you knowing it.

 This doesn't make sense (at least it's not a problem).  So what if two
 plugins add the same header?  Because the header is the array key, it's
 only added once, and because the returned parameter *is* the Header Name,
 they both add the same header that will return the same parameter within
 the plugin_data array.  So it's no problem.

 ...unless your patch does something different than mine did.  If you add
 "New Header", then

 New Header: foo

 gets us plugin_data['New Header'] = 'foo'

 It doesn't matter which one, or how many, different plugins add "New
 Header".  If it's added it's added for *all* plugins.  (And as most
 plugins won't have that custom header, they'll just return "".)
