IIRC, most of the code we have for walking back and forth through strux had
to have special-case logic to go up and out to the next level. Policy
decisions about whether to continue walking "out" like this can be
controlled by an optional bool argument, no?

Yeah. I wondered whether that approach would continue to work well when we
had to start editing.

I'm not sure I understand. It's pretty easy to envision documents which
will want to have multi-line headers and/or footers. (In fact I'm pretty
sure I've already hacked documents which used that feature.)
Does this not work?

Yeah. The biggest problem would be how to reflow the other containers on
the page as the headers grew or shrunk.
