Yes, at the moment. I don't have specific plans to change/fix things for
v6.4, but might be possible. It would be OK if someone else wanted to
pick up the coding and carry it forward...

I wonder if we can use the rewrite rules system to implement #1?

There was some discussion of this and at least one person thought it was
an ugly feature (this is available on Sybase, right?). So I didn't even
try to implement it.
