Federated commenting on podcasts

What is the problem you are facing?

In addition to issue #498 (closed): No way to receive or give the feedback on podcasts. Because of that, some podcasters who value feedback have to publish on Peertube rather than Funkwhale, which is not too great an experience for pure audio podcasters.

What are the possible drawbacks or issues with the requested changes?

I see no obvious drawbacks or issues with enabling (optional, of course) commenting on podcasts. Aside from possible difficculty in technical implementation.

Context

Comments for podcasts are relevant, possibly even more so than for music, as podcasts are more of a discussion medium. As a prior art, Peertube has federated comments: it receives messages from other servers and puts them into the comment sections of videos. But I think, we can go even further: comments with timestamps - much like SoundCloud does. Or time ranges - which nobody does! This way the commenting party can highlight points they want to comment on. and let the observer jump right to them.
