Would you prefer, then, that if someone makes a decision to (in your
opinion) "break", they not revisit that decision?

It's the real world.  Not you, not me, not nobody is ever going to be
happy with every decision anyone else ever makes.  Expect (or insist) to
be and you're just guaranteeing yourself a lifetime of frustration.  But,
on the other hand, for my part at least, when I can persuage people that
they got it wrong and should change their minds, I'm pretty happy -- I'm
not really sure what else one can reasonably expect (and because it is the
real world, not an ideal world, I can't reasonably expect to even always
get even that).

Sure.  I'm not sure, though, what that has to do with the inevitable fact
that some decisions will be made once, turn out to be wrong, and need to
be revisisted.

You say later in your message (snipped as this is already getting rather
long) that you wish technical changes would "go up for public discussion".
It looks to me like that's precisely what's happening here, and also like
the most probable outcome is that David's change will be reworked so that
the kauth interface stays opaque.

So what's the problem?
