Makes sense I suppose, but I'm still quite surprised by some of the design choices.
My general impression from looking through the information is that for many elements the team knew that something would need to be accommodated in the space but they weren't sure exactly how big it was, where its connections would be or exactly how much cooling it would need. Therefore they designed a space / cooling capability that would definitely be sufficient. No doubt by the time they did know it was too far into the lead time to take advantage of the fact.
This is all based on assumption from hearing / seeing what happened with the 2014 Sauber.
