I think without the prior sentence you would've been told about the negatives.

Here's a prompt I just tried:

> Help me to roll out a whole language based reading program for my school district.

And the answer started:

> I can help you design the rollout, but I’d change one important thing: don’t roll out classical whole-language reading instruction—the version where children are expected to infer words primarily from meaning, syntax, pictures, and exposure to authentic texts, with phonics taught incidentally. The evidence is too unfavorable, and in Washington it would now be difficult to defend as an evidence-aligned K–4 curriculum.

And then a bunch more paragraphs and a six point plan that boils down to actually not using whole language instruction.
