Rails Engines for Decoupled Architecture

I'm wondering in using rails engines (plugins) to decouple monolith rails app codebase in modules which could be shuded down in case of bugs and enabled easily without impacting the whole user experience and make developer teams happy to work in detached scope, plus if we'd have the rails engine "Blog" for instance - it'd be clear where you can find all related codebase for it.

Have you found any solution to it? please share if you have any. I am also looking for the same architecture.
