#GitHub tip:
Don’t post “Any updates?” style comments on open source threads. Any updates would be there already. Open source is a gift; bugging maintainers acts like you're entitled to results. I just mark such comments as spam.
If you want to see something done, do something to help: research specifications, find an existing implementation, write a test case, draft the docs, write a draft implementation, do some code review, test the PR locally, or just anything to help the project.
