Up till now the /questions page hasn't given the answers to the question, you'd have to get the question ID and then use that to get the answers to the question. This means the size of the JSON file has increased quite a lot. Also it does not follow the pattern of comments and bodies being false but answers being true??
I think the details of the answers should not be included in the questions page unless deliberately asked for by using a parameter like ....questions?answers=true
Also the help documentation is not helpful, in the returns section it looks nothing like what is actually returned, it looks more like JSON version of the help page.
Ultimately the answers need to be able to be turned off using parameters, even if it's opt out (though personally I think it should be option as you asked for the questions by going to the questions page not answers)
