Probably a lot of overlap with the same type of person who feels the need to justify every sick day to all their coworkers, like they’re afraid of being judged for being absent. (Yes thank you Jane I don’t care that you were up half the night with a plumbing issue, you don’t need to convince me that you’re tired enough to take the day off)
Also, IMO, it’s putting the burden of knowing and managing your schedule on the other person. You expect them to be paying enough attention to you to remember when you come back and to resend their request. That’s not reasonable.

This might seem obvious, but make sure you clearly state and restate the dates you’ll be out of the office. Even if you put the dates in your subject line, you should also repeat them in the message body. It’s hard to over-communicate here. State exactly when you’ll be back, and whether or not you’ll be responding to calls and emails while you’re out. If you’re on the road but are responding to messages, let everyone know if you’ll be unavailable for an extended period (while on a flight, for example), if you’ll be in a different time zone, and in general, that they should expect a delay in response time. All in all, set realistic expectations and strive to be as specific as possible.
Hoo boy, have I got some PTSD from Old Job about out of office autoreplies. Exboss was such a stickler for them and actually enforced her expectations as official policy. Meaning if you didn’t do it to her exact specs, she’d call you back to the office to do it (which no one did) and read you the riot act afterwards while threatening to write you up for insubordination. She demanded them any time that we were away from our desk for longer than 30 minutes and for anything other than a meeting. So training in the conference room down the hall, a work lunch with teammates, leaving an hour early for an appointment, arriving late for an appointment, even working from home, all required OOO alerts.
