I fully agree with the post. Except for a fast prototyping or a short personal script where it could be not necessary, type hint is a must. The subject is not only to guarantee that the program now runs without errors, but it will be still working right in the future too, even after a developer (either the original or other) make changes to the code.
After preview it will be a paid subscription additional to Office365, the same strategy as Office Copilot. I hate this policy of pay for a product then still paid for more functionalities… at the end of the year you will have paid a lot.
