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. - Paul
