Eh? Only case I know when recursion may result in crash is if it's endless
recursion (or recursion for all effective purposes can be considered
endless - like one 100M functions deep). Do you know more cases?
A recursive function, takes a mere 13087 iterations to result in a crash
and this is a very basic example.
$i = 0;
function a() { global $i; echo ++$i."\n"; a(); }
a();
A more complex function could take as little as 1k iterations.

Well, 100% of existing PHP code doesn't use goto either, so your argument
is not working.
Ok, so you propose that people start using exceptions for OO and
procedural code just because they are "there"? One major problem with an
exception, is that once it is thrown you cannot go back to portions of
code found within the exception block. This is why in many situations
they are not practical for anything but fatal errors.
