unfortunately, the main point is that web2py doesn't provide
"out-of-the-box" something that clarifies what a "flash status" is .
passing a status as a new header uses the same "tech" web2py provides for
other things, but since it's not in the core code, your shortcomings are
exactly what is needed.
