How about replacing "There is also no realistic use case for users to build a 32-bit
kernel on a server" with the following description:

"32-bit x86 is maintained for legacy reasons. New CPU features are generally
not enabled for 32-bit system, its test coverage keeps shrinking, and modern
32-bit distributions have become rare."
