Hmmm, I guess I'm confused by Thomas's statement...

"I refused to stop using test -a in my packages as well, and refused to
declare #!/bin/bash."

...and the fact that dash, bash, and test, all document their binary -a 
operator as having the same behaviour.

Is their some Bourne style command interpreter other than dash in Debian 
which offers to provide "sh"?
