Reading your entire response it sure as heck sounded like that, they haven't been responsive on all of them...
There's still a ****-load of unanswered/unclear things, but with the SDK out now a large component will at least start to become less murky, & through feedback can be refined.
Getting there, hopefully soon we'll also get feedback to all content in the docs, some of which -no doubt- has been cleared-up now, thanks to the recent site overhaul.
