This will only work to increase alignment, right? So what if we are decreasing alignment (but not all the way to 1)? I guess that requires #pragma packed or __attribute__((aligned(..))) which we don't fully support yet.

Yep. If one would try to decrease alignment it would lead to layout test failure... just as it is now.
