Great, there are a few different specs for geohashing - which one are you using? Sure, the event data would be helpful but I'm not planning to create a NIP for it. 

 I'll send you the spec later today. Perhaps I misunderstood.... when you said you'll add support for it what did you mean? 

 I mean nostraco.in will read the event and tag data and make it available on a map. If I like the spec, might also create events with the same format.
