Indeed. And they work fine the way they are. But they can be seen as
regular data (that's basically the implementation) with no real special

Very few of the operations are actually interested in the address space
structure. I don't disagree with exporting it per se, though. It's just
that it isn't generally that useful, and you _can_ get at it other ways
