PEAR(1)_Exception

Hey, I've read this page... http://wiki.pear.php.net/index.php/PEAR2_Exception_Policy Now, my question is, since PEAR2 is still a few weeks away, what keeps us from PEAR_Exception2 in the meantime? Reason why I ask is because the PEAR package itself is pretty hefty and I imagine that a lighter PEAR_Exception2 package would sometimes come in handy. This "package" could be really simple extending Exception with no other dependencies. Packages using it would just extend it - so basically just like PEAR_Exception, but bundled on its own. I hope I am not re-iterating on something that has been discussed (and beaten to death :-)) before. I couldn't find a reference, etc.. Cheers, Till
