That's because not everyone is always running bleeding-edge kernels. We have found and fixed multiple regressions in the kernel on ia64. As of Linux 5.12, the kernel runs fine on most ia64, there is still one known regression that affects some machines. Disclaimer: I'm Debian's maintainer for ia64 (and most other older architectures such as m68k).
