Yes, hence my earlier post. PU COG is mandated so the COG of the assembled mass is the is the goal not necessarily the locations of individual components considered independently. Vee or forward centerline locating, whether atop or splitting the ES, provides symmetry, which frees up space on both sides of the ICE beneath the exhaust ports for airflow or header routing. Rearward MGUK locating (if the legality box allows for it) would require a long driveshaft back to the front of the engine.
You only have 100MM of space there before it start protrude out the front, not sure that's enough space for the MGU-K. That's gonna be prime Fuel cell real estate there.
No, this is only a reference to the mechanical connection area. They want to continue using the nose of the crankshaft as the connection point, driven alongside the cam gears, hence it must be within the first 100mm of the ICE volume. There's no rules about where specifically within the PU volume that the MGUK needs to be placed (that I've seen). This why C18.5.7 exists--to provide the freedom of placement for packaging reasons with limited mass penalty. Hugging it right next to the ICE vs hanging it from the front of the ICE vs attaching it to the monocoque, etc., are all accommodated as teams/builder may find certain configurations more advantageous than others.
