Correct, but also with 1, there is a way to embed chapters into a mp3 file that's a part of the ID3 standard. We use Forecast (https://overcast.fm/forecast) to do it. I've found that most podcast applications either parse these chapters or timecodes in show notes (or support both), and that would be another way to identify moments that as a producer we've called out in the file.

for 2, the RSS feed would include show notes and greatly speed up the process for bulk production.

If you'd like to get in touch with me, I'm on twitter as @yakk0dotorg. thanks again!
