I think that's a very personal choice. Myself? I'd eat it up.. I've yet to get drunk off a bottle of bbq sauce or brats boiled in beer.
Someone that knows how to do it will post the info that actually the alcohol doesn't completely cook off. A lot of people, even other than alcoholics, need to know about and avoid alcohol no matter what (due to medications they are taking, allergies, etc) so that would rule out everything like aftershave and the like (and many alcoholics avoid EVERYthing like that too).
I don't personally stress about alcohol used in cooking.. it's when it's mixed in drinks that I totally draw the line
