Jose,

So pilots can evaluate their bag of alternate plans with an eye to which
would be more appropriate.


Ok, let's assume the controller knows there's an accident AND they have the
time and free mind capacity to say it on the frequency. Then what? For that
info to be useful, you'd have to know how long it's going to take to clear
up. I'd wager the controllers did not know that.
