I hope you read the posting I was refering to: there's always ease of use against security: some people prefer having the passwords stored in plain text, because they run a gallery with newbie-users who forget their passwords every now and then: it's easier to look up their passwords if they're plain-text.
If someone hacks your site and is able to see your database (e.g. gains access to phpMyAdmin) and its contents, you probably have to worry about other things anyway...
The main reason why this hasn't been done yet I guess is: it simply has been forgotten. There are so many features that are being considered when developing a new version: sometimes you simply forget about stuff you were thinking about before.
