The point is, it's impossible to bank on pointers being either 32 or 64

not exempt.

Doesn't align(n) work for class members? If it does not, it doesn't seem it'd be hard to implement.

The point is to eliminate the wasted padding by rearranging structure members appropriately. Since the amount of padding may be different between arch's, the layout often needs tweaking.
