I haven't used it, and last time I heard of it, it was still called bitwarden_rs. I like the project in principle since it capitalizes on BW's open API, and that's really good work in the spirit of open-source software.
Having said that: I haven't dug into it much. I don't know what the current state of auditing on it is, or how widespread adoption is relative to the mainline BW backend. I hope they use a database backend other than BW's default MSSQL, which has always seemed like a weird choice to me coming from mostly Linux, and so mostly Postgres and Maria/MySQL, though I skew heavily developer over DBA, and that distinction may as well be personal preference (as in, I don't have an intelligent reason to dislike MSSQL beyond my habit of using other things).
