I love Python and have been using it for 20+ yrs as well. I have seen a lot of pain on older Python projects (pre type hints). I think you need more discipline and tests and docs to keep a large Python project on track. Not saying you can't do it, it just takes more work than with a statically compiled lang. However as I said - type hints have (imho) a huge improvement for large scale Python projects.

as great as hints are they still don’t provide any compile time type checking nor even enforce the types. so they are exactly just hints. a statically typed python might be interesting

that's a good point but you do get warnings about issues (that you can block CI build on) and also much better IDE support
