That particular question, why the PAS import/export routine would try to
run those CMF steps, was exactly what I thought when I tried it all out.

I do remember that GS design discussion vaguely but never paid much
attention because I never used GS "in anger" and outside of the CMF.
It's not my goal to reopen that argument, but I'm left with the
impression that at least from the perspective of someone who uses the
setuptool ZMI to explore and use GS there are some expectation
mismatches and usability problems. Once you recognize the design
decision you can at least explain the behavior.

I'll continue down the path of trying to make the steps themselves more
resilient so I get somewhere.

At some later date it may be useful to review the current behavior. I
feel some decisions may have been taken with a too-narrow focus (CMF
only) because very few people use GS outside of the CMF or Plone.
