The problem here is that you're thinking of the 1/10 of 1% of our users
who have a serious PostgreSQL failure and post something on the lists
for help, for which XID forensic information is useful. As opposed to
the 99.9% of our users for whom deferred freezing is a performance
burden. While I realize that the 0.1% of users are more likely to have
contact with you, personally, it's still bad policy for the project.
