I think it would be best to leave the code as-is. The compiler will
remove it all so there's a very small amount of compile-time cost. We
could just comment the code out but then they would rot over time,

It could be a fun starter project but I have to say, befs is not a very
valuable place in which to spend your time nor is befs the best place
in which to develop familiarity. A more modest project within a more
mainstream part of the kernel would be a better investment.
