Any idea why Bitwarden insist on their installation ID generation for self hosted deployments? it strikes me as unusual, as it's not documented WHY it's necessary, or what the ID is used for, only that you're required to give Bitwarden your email address to get the necessary ID.

If they would remove this step, or at the very least explain it, I'd be more likely to deploy and use it. Critical things like password managers should be self hosted where possible, IMO, and this is a blocker preventing trivial deployments.
