TBH it sounds like a horrible hack.  Disable vacuum truncation?
That can't be a good idea.  If it were something we were doing
behind the scenes as a temporary expedient, maybe we could hold
our noses and do it for awhile.  But once you introduce a reloption
based on this, you can't ever get rid of it.

I think we need to spend more effort looking for a less invasive,
less compromised solution.
