I tried that once in the past, and did not care for that user experience.

If, if you want to do that with dlang/ repo's for the purpose of learn 
things let's start with dub as that is repo is in dire need of closing 
tickets and PRs.

But two conditions:

1. Stick to one PR at a time.
2. LLM's are a tool, you are still responsible for the PR (so self 
review and so on).
