The thing is, this continues to have the exact same issue that %pK has
- because it is opt-in, effectively nobody will actually use it.

That's why I would suggest that if we do this way, we really change %p
and %pa to use the hashed value, to convert *everybody*. And then
people who have a good reason to actually expose the pointer have to
do the extra work and opt out.
