I don't care much about the details, but I do think that it should
be difficult to accidentally install a new version of a pkg which is
incompatible with data files saved by the old version.  Since there's no
easy way to tell the difference between installing the new version from
scratch or installing the new version after removing the old version,
this implies that it should be difficult to deinstall the old version.
