I think that having just session start is still useful, even if I
encourage you to get session end covered, because yes they do form a set
:-) I don't think it's completely *impossible* to get session end to
work, only it needs to be run prior to any subsystem shutdown (I haven't
actually looked at the code, mind). Of course, it'll need to be clear
that it might not run in certain cases.
