Bro's event interface is primarily for realtime analysis which you get from sniffing traffic on an interface. If you are reading a tracefile, "real time" typically proceeds much faster than the wall clock and since Bro's communication protocol was originally intended for multiple Bro instances to communicate with each other things could become pretty badly confused if different Bro processes think the time is different.
Now, I agree with you that it seems like a very reasonable request for broccoli to be allowed to connect even when reading trace files (i've probably requested that feature myself at some point), but I'll leave it up to Robin or someone else to see if that's something that we could reasonably do (allow communication with broccoli even if reading trace files).
