Could be enabled by who/what? I think it is a bug that yocto kernel config is trying to enable features which are always disabled in the effective config, and this may hide real severe issues. I know do_kernel_configcheck ignores these currently, and merge_config.sh output is effectively ignored too, but improvements to that make the output useful and find issues like this. Modeling of kernel config dependencies in these fragments does not need to be complete and take all variants into account, but I think obvious issues in the used configurations like in the machines used by oe-core and meta-yocto should be fixed.
