Doesn't this create the same problem, albeit on a different pain point? Now the service/methods you use to sync and store your DBs are a problem without much benefit? I've seen people use keepass and then google drive, which just seems silly at that point if you're going to negate keepass' benefit (local management) just to attempt to gain some of the benefits of managed services like bitwarden in very clunky ways.
unlike the others where your only option is a single database, some keepass apps allows you to have multiple databases open at a time which means you can split up your sites/passwords depending on how important they are and have a different levels of security for each one.
i have 1 vault with any important things and the other one just has everything else and i don't need to worry as much about the security of it or worry about where its stored and if that's secure.
its also great not having to type in a long master password just to get the login details for some small forum where it really wouldnt be a huge deal if somebody got access that vault. half of passwords in that vault are there mainly because i want them to be autofilled, not because i need to keep them secure
