Thank you! I really really like Reason and have been using it for some time now! The experiment was mostly for the benefit of my colleagues and for me to share an experience of integrating Reason in a large codebase.

At my last company, we ran two Reason projects in production. We didn't have any type related bugs and us frontend developers loved the experience! The few bugs we had were due to mismatching types when doing backend calls, e.g. a field was nullable that we didn't know about.

Runtime performance is the same as a regular React app, since reason-react has zero-cost bindings to React! Apart from that it also feels really good to come back to a Reason project after some time away, because you've got the solid compiler supporting you.
