I don't think realurl will break in 4.2 if this gets added.

I think the "problem" is in function tx_realurl::setConfig, where this
is called:

	// First pass, finding configuration OR pointer string:
	$this->extConf = isset($extConf[$this->host]) ? $extConf[$this->host] :
$extConf['_DEFAULT'];

But $this->host is the current host ("TYPO3_HOST_ONLY"). If the link
points to a page in a different sys_domain, which might even have
different realurl settings, the wrong setup is loaded. With the "new
parameter" in place $this->host isn't always "TYPO3_HOST_ONLY", but the
domain where the link is pointing to.

Or am I misunderstanding the code or is this being handled somewhere else?

Cheers,
