Split off from #16:
I maintain the pin-init-next tree of the kernel. Every release, I check if my testing configs are up to date, as I want to compile-test all Rust code in the kernel. For this purpose, I'm currently using make menuconfig and then use its search functionality: pressing / and then typing RUST to find all the options that mention RUST. This doesn't actually find me all the options that use rust, but only the ones that have it in their name.

It would be incredibly useful if I could query which options directly (and indirectly) depend on another option. In my case, I'd query for RUST and direct dependents. In addition, it would further be very useful to filter out the options that are enabled in the current .config. This way I only see the options that I have not enabled, but that depend on RUST.

This doesn't actually find me all the options that use rust, but only the ones that have it in their name. It would be incredibly useful if I could query which options directly (and indirectly) depend on another option. In my case, I'd query for `RUST` and direct dependents.
