I have seen it. I'm open to using it at some point, but podcast-partytime works well with our full-stack JavaScript infrastructure.
I'm thinking it would take me a day of work to add the missing pieces we need to podcast-partytime, but switching to feedparser which is written in Rust would be a bigger initiative.
partytime logic is only used in podverse-parser/src/lib/compat and podverse-parser/src/lib/rss, so swapping it out doesn't seem crazy difficult
