It's like when my code blew up on a S0C1 because the customer was running on too low an architecture. (Yes, pre-sales was supposed to ask but forgot.) My boss said "can't you put in an error message for that?" and I said "S0C1 *is* an error message." (Didn't fly.) Regarding H'0' as a termination routine, 0 is architecturally guaranteed to always be an invalid opcode, so I say it passes the "bite" test.
