I think the change to using names does make things a bit more confusing 
for users, but it opens the door for us to greatly improve reliability 
of scripts in the long term and generally it feels like a nice way for 
analyzer authors to deprecate functionality without needing to create 
all new events.  In my opinion even though there are hairy side effects 
to this I think it's a net positive.  It would be great to get case 
sensitive versions of dns events and the http header event.  That has 
been a very long standing deficit.

I guess if there is some more obvious way to do it could make sense, but 
I haven't been able to come up with anything after thinking about this 
for quite a while.
