Only for RMS values of "should". And these are values I very much respect, and I promise I won't act surprised when I get screwed by using proprietary software

Only for RMS values of "should". And these are values I very much respect, and I promise I won't act surprised when I get screwed by using proprietary software. But in terms of user experience, I can't inflict KeePass on the people in my company, especially any non-Windows version. If you want to train people to handle passwords responsibly, user experience is extremely important, and having to use KeePass would be a punishment. People would start finding ways to not use it, which is why 1Password is the safer choice in practice, despite being proprietary.
