If I understand correctly, this project is the upstream source of man pages that document system calls, special files, libraries functions, and other interfaces in the kernel.
Perhaps the impact will be these pages will no longer be updated as frequently, unless someone takes over?
Anyone who does system administration on Linux, who uses the command line, or who programs in C is relying on this documentation.
Also, it is not the Debian package maintainer stepping down, but the project maintainer.
