If *your* script has a dependency to run using *dash* instead of *sh*
then you _must_ use #!/bin/dash anyway. And what I _*I*_ don't want
dash as /bin/sh? You see not everyone in the community will agree. You
can make the suggestion to those using your script to do so otherwise
but forcing dash as /bin/sh worldwide isn't something you can actually do.
