Alright, I went through the thread and compiled summaries of all the suggestions into a Gist: <https://gist.github.com/j-james/08cd36b7475d461d6291416381ce98ad>
I did a best-effort attempt to break suggestions up by needing breaking changes or not: but if I categorized any wrong (or misrepresented them in the summaries), do let me know. Hopefully that's a little more compact than scrolling through the entire thread.
