Following the process of phasing out Intel 486 CPU support and other old hardware drivers that were dropped in the Linux 7.1 kernel cycle for reducing the kernel maintenance burden, the upcoming Linux 7.2 cycle is continuing the trend of phasing out some of the old hardware support that is very obsolete, likely having no users on the latest upstream kernels, and no one formally maintaining the obsolete drivers...
