In this case, the 'break' is only damaging if it is in the query
path.  If it is not, it ultimately reaches the expiry timer and
becomes a non-issue for all involved.

Perpetual entropy leading to heat death is not acheived.

So, serving a zone that has a very large expiry on a recursive
nameserver is, in effect, putting your hand on the burner.

Remember I'm on both sides of this fence;

Either use a low expiry on zones hosted by recursive nameservers,
or use any (probably large) expiry on authoritative-only servers.

Then I guess you won't be a fan of:

Above is an example of a software engineer (Mr. Andrews) choosing to
experience a kind of pain now (the ietf standards process), for others
to experience a kind of pain later (those who use rfc1918 space adopting
software implementing this), and for the as112 operators to experience
less pain until gradually it is retired.

Pain in this universe is absolute and eternal.  All you can do is
choose for whom it is fair to experience how much of it.

Something like the Cyclops in Krull.  Choose to get left behind in
the field to die peacefully, or get crushed in the stone doors saving
your friends.

The mechanics of the result is unimportant.  The choice is.
