The key thing is that if the move to dash-as-default - or an upgrade of
dash whilst it is the default shell - fails, that should not leave the
system without a working /bin/sh.  Having it not be a shell script seems
a reasonable why of achieving that. :-)

Yes.  dash's preinst (in 0.5.5.1-7) currently has a /bin/sh shebang,
however.
