We used to do this at my old job in addition to OOO messages. I found it useful to know in advance how long people were going to be gone. There’s nothing more annoying than needing something urgently from the one person who can help and then getting an auto-response saying they’re out for the next 2 weeks.
Part of me would really appreciate an OOO that says, “I can’t get back to you today because I’m out robbing a bank.” Part of me would dread that, because I’d probably become that person’s court-appointed attorney.
