  When did we have one? Where did it go?

English is difficult and it is not my mother tongue.

I meant:

   If we had (would have) a post-authentication hook ...

We had discussed the post-authentication hook in connection
with role based skin selection but we never had it implemented.

  Such a hook would be extremely helpful for other applications,
  too.
  
  Yeah, a specific example that springs to mind is the selection of a CMF skin 
  based on a user's role...

Indeed. That where the post-authentication hook idea came into existence...
