Policy 10.4 says:
If a shell script requires non-SUSv3 features from the shell
interpreter other than those listed above, the appropriate shell must
be specified in the first line of the script (e.g., `#!/bin/bash') and
the package must depend on the package providing the shell (unless the
shell package is marked "Essential", as in the case of `bash').
So bashisms are allowed in maintainer scripts only if they invoke /bin/bash
as the interpreter.
Or do you mean something else by "ban", here?
