I'm wondering if I missed something in the docs - is there an easy way to have multiple rules share the same option flags?

Any rule should be able to request any subsystem's options.

It would belong here, which could use a little more body to help answer your question more clearly I think 🙂 https://www.pantsbuild.org/docs/rules-api-subsystems#using-options-in-rules

awesome. I was just going to try this so glad to hear it should work 🙂
