While I respect your points of view, our defconfigs are oriented towards
kernel developers. This is particularly important when right now the only
RISC-V hardware on the market are test chips. Our expectation is that
distros and benchmarkers will create their own Kconfigs for their needs.
Going forward, we'll probably add a few more validation and debug options,
as Palmer suggested during the patch discussion.
