It mentions running on Wheezy, which from a bit of digging looks like the 2013-2015 version of Raspbian, based on the 3.x kernel. Wheezy is only listed for the 1/1+ and 2. https://minecraft.fandom.com/wiki/Pi_Edition lists it as being slightly stripped down from Alpha 0.6.1 of Pocket Edition.
Also a quote from 2016: "The original team has stopped supporting it and starting with 0.9 MCPE became a lot more ambitious technically, which also means that it became a lot harder to strip down to run on a Raspberry Pi. Actually, we finished removing all Pi related code to reduce complexity in 2015."
If your interest is simply in running MC on a Pi you're probably best off looking into Java Edition, though I have no idea how capable the hardware actually is graphics-wise. If you're more interested in MC on cheap hardware, you're probably better off with a cheap Windows machine and the Microsoft Store/Bedrock edition written in C++ for performance.
I'm not sure how impressed the average kid would be comparing dated, underpowered with current Minecraft
also, I never understood the meme but can it run Minecraft? since the game engine and mods can be pushed as far as you want on latest high-end hardware, and does struggle/gives bad playability on low-end hardware
that said they have made an outstanding effort to at least make the game run on potatoes, even if it looks less glamorous
I think the "can it run" bit is more with Doom, which runs on all sorts of absurd things (arguably including a lamp, but I don't think it counts if you actually have to mod it to add a display).
