What I'm more worried about is the copyIDs, because it's easy to fall
into thinking that higher ones must have been committed after lower
ones. Of course, anyone who's done their homework will know
otherwise; but I think there's value in being friendly to those who
haven't done their homework too, since you never know who will need to
track a bug down into the filesystem. (n.b. I'm aware that the point
being questioned was whether or not this is more "friendly", not over
whether being friendly is a Good Thing :-) ).

Heck, txnIDs actually can be ordered reliably by their keys, at least
if you're trying to order which txn was opened first, not which was
committed first. Why anyone would want to do that, I can't imagine
either.
