For the same spec it's likely to be a different chip count rather than density. In theory two sticks could have higher bom... not that consumers would see such savings given the price segmentation where the appetite for higher capacities has deeper pockets.
Have recent boards/cpus fixed the instability problems people had with 4 sticks of DDR5 yet?
I was shocked when I saw folk saying you can't use 4 slots. It would mean that a one stick build would have an upgrade path but if you started with 2, you'd have to replace them.

Not sure quite what's going on with that project but when I looked - gpodder.net was a subscription service and the foss project was somewhat hidden and renamed as mygpo. Felt a bit suss and abandoned although I guess an rss server could just be "done".
There is also opodsync that seems to be a bit more alive and popular and says it's gpodder compatible. Not tried it though.
My enthusiasm to self-host my podcast/rss feed was killed dead when I gave nextcloud another go since it can apparently do this. Every few years I set it up having forgotten that the last time I did, I swore to never touch it again. I can't believe it's still such a bad experience.
