The first bullet point is key. A tiny minority of users care about their private keys, matter of fact worse than that, most people store their keys unsecurely, they are better off having a trusted admin handling their keys securely for them. There is no argument, beyond the moral high ground some teams think they have, to not have a centralized key manager (boo, the ghost of centralization 👻)

Yet another user guide reminds me of this XKCD about standards:

Maybe we don't just need a new guide but we also need to NUKE and remove old ones so they don't confuse new people.

The search engine is probably difficult because Hive has awful search operations, it is the reason we can't have an algorithmic feed. The architectural decisions are showing its age.

Great, instead of 6 figure DHF proposals sell plushies to fund their projects

I've seen AI do incredible things

In general I support AI aided development but we need to thread carefully not to shoot ourselves in the foot with code and feature quality. AI doesn't scale that well over long periods of time, it can start and produce stuff 800% faster but eventually, because of technical debt and feature creep, it drops to 20% and some researches even show it can SLOW DOWN DEVELOPMENT (if used properly caring for quality)
