Yes, ignore that question -- it's not relevant to this thread.

I'm not saying it does. I'm raising the possibility that selbri
that currently have "that x is true" as part of their definition
could be redefined as having "that x is actual" instead. I was
asking whether there are cases where that wouldn't be feasible.

In practise, it's very hard if not downright impossible to tell
whether a sumti should be a ka'e nu or a du'u.

As I say, I'm not saying they're the same thing. I'm wondering if
we can use one to the exclusion of the other, given the extreme
difficulty or perhaps even arbitrariness of deciding which to 
use with a given selbri.
