This is essentially just native_event() spelled differently. We've been trying
to take a principled stance on removing that.

If did want to break that principle, the right thing to do would be to allow
NativeEvent to be an opaque pointer in ozone builds and add a generic way to
build a ui::Event out of it.

However my sense is still that we should concentrate on removing it.

Yes, but there are some messages that need to be passed up to the window
implementation as-is. I could add ET_FOCUS_OUT, ET_EXPOSE, ET_CONFIGURE,
ET_CLIENT_MESSAGE and appropriate structs... but those are still X specific
abstractions anyway, and CLIENT_MESSAGE is just another name for NativeEvent too

     case ui::ET_LAST: NOTREACHED(); return std::string();
     // Don't include default, so that we get an error when new type is added.
   }
 #undef CASE_TYPE
 
   NOTREACHED();
   return std::string();
 }
