Fair enough. But a.out is long gone now and anyone who runs Linux/m68k these days does that as a hobbyist. I think that the advantages of fixing several dozens of alignment bugs once and for all hugely outweighs the disadvantage of breaking compatibility with old binaries. If I understand correctly, there was an (unintended) ABI break on Linux/s390 as well and it seems that it was not reverted [1]. Maybe someone involved in this discussion from back then can comment.
