Unfortunately not. It is so closely tied to our applications.
I don't know if you're at liberty to discuss further, but how has it been scaling a giant Rails app? Have there been any pushes to break it up into smaller components? Ie. fast moving stuff stays Rails, core infra moves to something statically typed?
We try to stick to ruby/rails since so many people are comfortable in that environment. We try to balance the desire to break pieces out with the fact that it lowers the number of devs qualified to work on it.
