'It was just several years ago that the open-source ecosystem began supporting the x32 ABI ...'
Many people (including myself) wondered about the point of that at the time. For those who don’t know, this ABI uses AMD64/x86-64 instructions, but with only 32-bit addresses. Something about getting the benefits of the more modern instructions and larger register set, but without the overhead of full 64-bit addresses. I think Intel was the main one pushing it. Moral: beware of features that are mainly of interest to certain large corporates, not to the community at large.
