For a podcast app that's a feature, not a bug.
Taking notes makes sense to me for podcasts. Syncing with https://Readwise.io makes sense to me too.
I think most people listen to podcasts for fun and entertainment so it's unlikely they'll want to clip, get transcripts etc. But the small number of podcasts doing deep dives on scholarly, technical or professional matters? It's potentially quite useful to be able to get transcripts/excerpts with highlights and audio clips to add to personal notes for future reference.
Reading about how they were sold in 2018 to NPR explains A LOT of why it hasn't changed much in the last 4 years.
Plenty of good and useful features have been added to podcast apps since the first one shipped.

Snipd looks interesting. May be my 2022-2026 daily driver.
