Does anyone know why it is only supported for a Model 3 B+?

It uses some extra pin headers only available on that model. I don't have a PoE hat nor a PoE switch handy, but I'd love to measure the output from the hat. Either way, I imagine there's good reason…

The extra pins break out the center taps from the ethernet transformer, so that the power can be sourced directly from the existing LAN connection on the Pi.

I really do wish the title was correctly capitalised -- I was wondering if my Raspberry Pi was going to start beating like a heart and slowly drive me to insanity.

For what it is worth, the capitalization was correct when I submitted it.

Unlike Alexa, every time you ask it a question it replies “Nevermore.”

Nice to have an official HAT - I've been using PoE splitters without issue for the last year or so now (on Model 2 B+ and Model 3 series) as an alternative.

Given the cost of this, that it adds a fan and uses some pins, a simple splitter seems like a no brainer to me!

So you give up the gpio pins, and you give up silence (+fan)?

Maybe a 5.1v poe splitter might be a nicer idea.

Is it still absurdly priced? I got bored of waiting and ended up buying $6 5v 2A splitters from AliExpress.

$20 thru Canakit.
