Yes, since I'm still here, that's my position too.
Our general position on consistency is that we'll try our best to
keep native mode compatible, while with sh compatibility we'll
try to be like other shells and not worry so much about what zsh
used to do. But it's a little bit of an odd case here for all
the reasons I won't rehash.
