When using $.get() or $.ajax(), the callback processing ignores WAActionCallbacks. This is implemented in WACallbackRegistry>>#handle: , resp. WAActionCallback>>#isEnabledFor:.
So there seem to be two options:
a) make sure I register some Ajax callback for each link in my hit list
b) find a way to simulate clicking a link that doesn't involve Ajax / XMLHTTPRequest
While I might be able to implement something for a), I'd prefer b) for flexibility reasons.
