   > I'm no longer sure if #346 or even the `guacLogout` event are the way to 
go for this
   
   I can't help but agree. From what I gathered, `guacLogout` in its current 
shape is useless for the purpose of this PR.
   
   > Hooking into those events and redirecting the user would potentially 
preempt tasks which are chained onto that logout promise, but which naturally 
would happen after guacLogout fires.
   
   Exactly. Or the other way around. It creates a race condition.
   
   > Perhaps there is a way to know that the user has just logged out within 
the handling of that CAS token field
   
   I'm not really familiar with the architecture here - but couldn't we 
"hijack" the logout logic by exposing a custom action/function from the auth 
extension and ensure it is called _after_ deleting the token, if defined?
   
   How do extensions typically extend core functionality? Is it always via 
events?
