Besides compatability issues, there are security issues with it. Of course, to maintain backward compatability (Superglobals are only supported in 4.1.0+) you might want to use the $HTTP_POST_VARS, $HTTP_GET_VARS e.t.c. which are being phased out however. Remember though, 4.1.0 was released on the 10th of Decemeber, so there's a good chance many hosts have upgraded to that version or greater, but there are always the late ones.
