Sure, all it needs is a specification with the same rigor as Posix's.
There have been a couple of attempts to do that so far, but they haven't
been articulated well enough to differentiate from set -e or to
implement.  I encourage folks to take another shot at specifying their
requirements for something `that actually makes sense', and `not sucking'
isn't sufficient.
