It didn’t look outdated to me, but is kind of weird and hard to get used to, though I eventually did. I don’t know how to make an export from Bitwarden to take into KeePassXC, though… I’ll need to look into this. Perhaps it can’t be done from the browser alone. Anyway, thanks for sharing.
Off-topic: do you have a guide on how to get uMatrix to do this blocking? That sounds great but it looks to be all manual. Do you run it with uBlock Origin?
