Just like HA here, I think that it is not recommended because it is more on the “self-host it” to have a good enough experience.
There are definitely some shortcomings as you mentioned, like with the Passkeys etc but it is indeed quite good in its own category, especially when compared to Psono/PassIt etc…when it comes down to password sharing.
So yes, it’s good but requires you to either self-host or be a business with somebody tech-savvy enough. In which case, you’ll probably be using Bitwarden anyway. 
Hence, the target audience is quite limited and doesn’t really fit the “single individual who would like ease of use + FOSS + privacy respecting tool” scenario.
