To me, it doesn't sound any more ridiculous that applications having specialized support on different architectures. Most applications get away without it, but when performance really matters and general-purpose abstractions aren't sufficient, having special cases seems okay—especially when there's only a small number of architectures (or filesystems) to handle. This can go too far—I still remember web development a decade ago—and I would prefer to have perfect abstractions that never need piercing, but absent that specialized logic seems _fine_.
