I don't think it's a case of 'listening', I doubt the features were made overnight because of views expressed in the forums. This is why it is better to wait to see what is revealed instead of getting worked up about what hasn't been revealed and what might not be there. I saw a petition to include an exporter, which was unnecessary as it always existed. Scirra are just keen to use this slow reveal method and it has only ever been good news for C3.
Scirra stated in the past that they were making no exporters whatsoever. The backlash was because of that, since not only we thought there would be no exporters but you'd have to pay $99 a year for an in-browser engine.
This is great news though, but still I'm waiting around to see how good it is. I feel like Scirra makes everything "thinking in the future" so I'm afraid their iOS/Android exporters won't work properly (or make the games slow on phones) for the first couple years.
