But this is where it becomes a power thing. The OOO person says that everyone else wants stuff from them that the sender can’t get elsewhere and you need to grovel to get it from them.
A clear, thoughtful out of office message saves the caller from troubles and inconvenience caused by your unavailability as they know what they should do next. Such a system avoids the negative impact that could come from the inability to respond to calls and messages. Your clients would likely try and contact you again and again, getting frustrated and losing trust in your business.

This OoO has to be in the tech sector. I can see something like this as an (internal only) OoO at my workplace. I actually kinda love it. Yes it’s wordy but it also makes the recipient take a beat and consider the importance of their issue and where to go if needed. It will also cut down on interruptions to the “catch-all” person in the standard OoO, which is generally the Admin. I have always hated being the go-to on people’s OoOs. I spent more time trying to find info on what Urgent Emailer insisted was URGENT than I did doing any actual work. And the urgency was never really necessary.
Again, this will depend HUGELY on what sort of role it is (an external-facing vendor, for example, should probably not use something like this). But for many internal requests, it is not power-tripping to ask someone to either redirect their email or wait until a later date to send it.
