What's a nicer way to do this? Without having that all_data array around?

I would do this recursively. Recursion + async is a tasty combo.
I haven't run this, but consider something like this:
function get_all(initial) {
return ajax(initial).then(function(result) {
if(result.next) {
return get_all(result.next).then(function(inner_result) {
inner_result.push(result.data);
return inner_result;
});
}
else {
return [result.data]
}
});
}
