Perhaps, but I still wouldn't want anyone prying into my private stuff (while I'm alive).
Also, tracking back, what I'd need to store somewhere (hence I asked "Where?" originally) is:
- password to password manager
- password to encrypted laptop
- password to email account (not stored in password manager)
- frequently used PIN codes (mobile screen lock and various apps)
I could store the PIN codes in the password manager to make things a bit easier, but I'd still be storing the two passwords somewhere that can unlock my online identity, plus the laptop password that unlocks some really private stuff. None of these would be acceptable to me to get into the hands of a nefarious spouse, whether or not I could sue for it later.
As to "Where?"... an alternative to the Bitwarden feature could be to store these passwords using some sort of 3/5 multi-sig encryption with friends and family members where they'd have to collude in order to get a hold of my stuff. But I wouldn't want to give them access either, my spouse only. But then again, what if we both die in a plane crash?
Perhaps there's no optimal solution. Maybe the good ol' lawyer would work. Give a lawyer the passwords, along with contacts to hand over the information in an order of precedence, like spouse->brother->mother->friend. If something happens, give first person alive in the list the information in X weeks.
I dunno about you, but I kind of got married to them because I trust them.
