Why was G34 added here? This is the G28 page, so it should be G28.

because G34 does G28 before it does anything else, and therefore an additional G28 is not needed. see also HOME_AFTER_G34 |

Lots of features will home if needed, so I’m not sure adding G34 here makes sense.

I now see the comment in G28: Homing is required before [G29](https://marlinfw.org/docs/gcode/G029.html), [M48](https://marlinfw.org/docs/gcode/M048.html), and some other procedures.
IMHO it would be worth it to figure out which procedures auto-home if required pr prefer to fail first, maybe standardize this
