I feel pretty similarly. Our product used to be a Python/Django monolith and over the years we've ended up pulling so much of the functionality out into services written in golang. It was fantastic for getting the product up and running relatively quickly, and we're still very happy to let Django take care of the frontend and database migrations. But when your codebase has gotten big, refactoring in Python feels like Russian roulette, and when you're doing a lot of background processing, celery feels like the wrong tool for the job.
