ArrayObject includes actual implementation, and the interfaces it 
implements activate special behaviour in the core.

SplObserver and SplSubject appear, unless I'm much mistaken, are 
equivalent to about 4 lines of userland PHP each defining 2 very simple 
interfaces. That's exactly the kind of thing FIG is working on, e.g. a 
Logger interface. I can't think of any reason, now that FIG and Composer 
exist, that those interfaces would need to be compiled into a PHP extension.

Not that I'd argue for their removal, now they do exist, but I see them 
as an old experiment in pushing coding standards using the core of PHP, 
and not a useful model for anything new.
