I see what you mean but I have never found it to be an issue even in large codebases. Sorbet and RBS have been problematic. Lots of development slows down with these solutions. I wished it had something baked into the language as well but I'm happy without... just following conventions alone has worked really well for me.

Yeah I just can't go back. How fast you can confidently refactor and the improved tooling is the biggest thing for me

You can do fine without them - Basecamp proved that. There's a good reason basically every other Rails company eventually moved to static typing though
