Amen. I have a co-worker who’s out of office message is always “spending time with my kiddos.” I don’t care. Just tell me who to contact and/or when you’ll be back.
As to who you choose, you might consider listing a coworker, your supervisor, or an on-call number if available. Just make sure to clear this with whomever you pick as a support person so they’re aware they’re backing up your calls and emails for emergent situations.

I personally like it. Of course, the emails that I’ve seen still say what to do if the matter is urgent and needs to be handled now — but as a person who gets 100+ emails a day, whether I tell you I’m deleting all of them when I get back or not — if it is in the thousands of emails that might accumulate in the time I am off, I’m not going to see it or respond. Better that I tell you now that you are going to have to resend the email after I return (or get my backup to handle it now) than you sit around waiting for a response that is never going to come. It is actually pretty common in my industry for any absence two weeks or more.
