A common way to use `pass` is to store things like `organization/domain/username` so for example it might be `goldmansachs/github.com/alphacoder` which is telling us that you do some work for Goldman Sachs who store stuff on Github and your username is alphacoder.
It doesn't leak any metadata because everything is contained in a single file and it's compatible with the rest of the KeePass ecosystem.
