Well my initial patch does exactly what I was asking for without overhead.

It's returning "false" [instead of throwing an exception] if an 
extension isn't installed - which is pretty clear for me. I know that 
throwing exceptions is a powerful tool in certain cases, but within the 
localconf.php context I'd prefer not to have exceptions since this might 
break complete installations just because someone uninstalled a certain 
extension.
