Only if the information made thus available itself constitutes a security
breach, which is not necessarily the case.  Knowing how much water someone
consumes or how many cans of Coke remain in a distributing machine would
probably not be a security issue for most users, just as answering a ping on the
Internet today is not considered to be a security breach by most people (and
those who do consider it so can block it).

My point remains, a globally meaningful address
is something that should only be applied when it
is useful for that endpoint to be globally addressable.

Unfortunately, if no provision has been made for a global address in the first
place, it may not be possible to put anything in place as quickly as required if
the need arises, and for critical applications, this is not acceptable.
