I guess the best we can say then is that D&L introduce a very bad model and then demonstrate that it doesn't fit the data.
Yes, it's a strawman.
I'm not sure that they intended it to be a 'correct' model
They say "the best we can do", so I'd say that they simply didn't know better. I'm convinced that this section would look quite different if they'd write it today.
The disagreement appears to be just how incorrect it is, yes?
Of course. D&L claim incorrectly that the "Doppler/SR interpretation" is ruled out by 23 sigma by SNIa observations alone, I (we) say it's ruled out by ~3 sigma. Taking other observations into account, I think we're rather getting back to 23 sigma.
