TTL decrement issues are fairly common across multiple vendors and hw,
can be sw can be hw limit. Common issues for example is if MPLS egress
PE receives explicit null labeled packet, it may not be able to
decrement TTL.
I may lack in imagination, but I struggle to envision a situation
where people decided to do this and then decided to be sneaky peaky
about it.
