I think that's a fine position to take.  We have found some fun bugs in
our testsuite via zsh's sh mode, and zsh (in sh mode) is a valid shell
according to Debian's /bin/sh rules, so I think it's fair to address
shell fixes for it in sh mode where we can, even though it sounds like
we'd prefer to skip the zsh mode.
