The motivation is performance (time and space) rather than just
"additional expressiveness".  A point with two 16-bit coordinates
can fit in a single 32-bit register and can be used very speedily;
forcing it to be accessed via a pointer would double the memory
cost on typical machines and slow things down substantially.

Potential for extremely high performance has always been very high
among C++'s design objectives, even to the detriment of simplicity,
generality, and other nice concerns.
