I'm still thinking about how to document this stuff. I'd like to write a
man page which defines and describes our SDT probes and provides
examples. A wiki would be a good place for examples, but I'd rather not
document stuff there as it'll eventually fall out of sync with what the
code does.

Yep, it'd be good to have somewhere to document outstanding DTrace work,
missing features, bugs and so on. I'll document all of the problems and
shortcomings that I'm aware of, and add a wiki page for them (or append
to an existing page).
