Which makes me think -- the ABI will have changed by adding three new
pointers to the end of the main struct, yes?

Of the options on the table, do any of the others involve adding three
new pointers? What I'm getting at is that while the API and symantics
may change with a different NA system -- maybe the ABI won't change as
much (even if those pointers mean something different, but the size of
the struct could be constant).

Or is this just a fantasy?
