AFAIK, setup has always behaved this way. It first uninstalls the old
versions of all packages being upgraded (that's how the old pdksh.exe got
unlinked), and then installs the new versions (creating new files,
essentially). It never did overwrite the file in-place. Changing this
will probably involve radical modifications to setup's internal logic.
