You know, either one of those alone would be scary as hell. Both in
one patch seem to me to be sufficient reason to reject it outright.
Not only will it be an unending source of bugs, but it's chewing up
far too much of what few remaining degrees-of-freedom we have in the
on-disk format ... for a single purpose that hasn't even been sold as
something we have to have.
Find another way.
