In the spirit of transparency, this item is not being actively developed. There is a prerequisite engineering effort around item-level encryption (which would enable vault item sharing), which is still in progress and requires careful migration of self-hosted customers to follow this new encryption scheme. We absolutely see the need as we want to expand our general sharing capabilities, which also includes making it easy to spin up collections when sharing items with one other person. We’ll provide more updates once item-level encryption has completed migration for the entire Bitwarden base and if this work does get picked up.
