It may also explain, thermal load, why Bosch went with an all aluminum design, including for the bore, instead of cast iron like on a CP3.
If I were to guess, the reason for aluminum is mostly to do with cost.
It is much cheaper to cast aluminum, though the thermal properties is an added bonus.
Their key bragging rights is the pump is both cheaper and higher pressure.
We know they deleted an intermediate stage (gear pump). That is a very big chunk of the cost factor right there.
It did occur to me that with heat... deformation of the casting is a distinct possibility.
If you ever see a stronger / reinforced casting in later versions, that is your clue.
