While you're at it add the USBC power hack https://github.com/vk2diy/hackbook-m4-mini

I've been traveling for business with this as my sole machine for 3 months straight and it has proven to be an excellent system.

I wonder why Apple left those two large power pads? They don't look like typical test points.

Are the populated from the existing PSU input or just there in case anyone wanted to mod it?

They probably use them in production as test jig connects for passing power. They are vertical inter-board rails. When making physical connections for high current contacts it pays to have a larger surface area in case there is a poor connection as substantial draw may occur for short periods. Also, such surfaces may degrade over time, so extra surface area is desirable.
