The reason for this behavior is that in PHP 3 and 4, objects were treated very much like arrays (this is the main reason for redesigning the object model for PHP 5).
I don't think that the old behavior is correct and an empty should always return true (i.e. empty($var) should return true if the variable is NULL and false if $var is an object).
I don't think we should by default support the PHP 4 behavior because it's just not right. What I suggest is to either break BC completely or support the old behavior in compatibility mode.
What option do you prefer?

zend_execute.h, lines 95 - 98:
case IS_OBJECT: /* OBJ-TBI */ result = 1; break;
I have a patch, but that includes a TSRMLS_FETCH() - maybe it would be wise to change:
ZEND_API int zend_is_true(zval *op);
to
ZEND_API int zend_is_true(zval *op TSRMLS_DC);
but that breaks the API.
