I don't self host anything where it would impact me unduly if it went down while I was on holiday to the point where I'd have to break state and fix stuff.

A password manager falls in that camp so it's paid-for Bitwarden every night every day every possible way for me.

Sure Vaultwarden suits others - generally those who either want control of their data, smaller target on their back than a public instance user, watching their pennies etc.
