It's three engineer years until 2025, and it's just a person mentioning on the discuss board. It sounds a bit weird to throw something like this in a public forum.
Why weird? The request was made there. The discussion on the PEP is there. And the person answering is a core Python dev and part of the Python team at meta/insta.
Their team wants it, and is offering hours to help get it done. Is this not what everyone wants from businesses using OSS?
