Gary,

I think that the answers to questions (1) and (3) are still YES, but  
I'm afraid that I've been out of this for too long to answer   
authoritatively. Perhaps Gary B. could confirm this?

The original reason for (2) was that way back when the bridge was an  
"experimental" feature under active development. Now that  people are  
using it and it's not changing, it probably makes sense to export the  
such symbols.

Randy
