By now, you know that your idea has been rejected, but it came with suggestions for any future ideas. You thought you could be more useful if everyone gets it in the same way, but that will also cause more maintenance burden to the upstream authors in the future. I personally tried to stay with you during this 5 year+ long journey. A lot happened in life during that time. You helped me to make new friends, and helped many young ones during the workshops.
Even though formally the PEP is rejected, the implementation will be updated as required. You helped before, and you will help many in the future too. Just the way to reach you will be different.
