No. *I* *must* wait until it's usable. I have circuits to simulate  
*today*.

I am not opposing Verilog-AMS. Why do you think I am? Mostly what I'm  
saying is that I won't dive into an empty swimming pool. There's also  
some skepticism at your hard sell: In a long career I've seen too  
many universal solutions that were going to solve all our problems.

Until Verilog-AMS completely takes over, we must continue to support  
SPICE. Right now that's what's getting the work done.

And yet they aren't "putting their money where their mouth is" by  
publishing Verilog-AMS models in their design centers. So of course  
there's little support from gEDA users: we have circuits to simulate.  
We can't wait for pie in the sky.
