Because lots of people were fighting it and I am therefore still collecting
data points to justify the alignment change. That's why I created the WIP
wiki page.

I will add more information to this page. One important data point is that
there was an unintentional ABI breakage on s390x at some point where they
still went aheadwith.

Well, the official SysV ELF ABI by AT&T uses 4 byte alignment, so I would expect
any *nix flavor which adheres to the official specification to use 4 byte alignment.
