Consider adding config for DataSource::removePasswords()

[ssnepenthe]

I am currently working with WordPress which uses "pwd" as the password key.

Not the end of the world - extend and override works fine.

But it would be nice if we could configure keys or patterns for keys that should be considered sensitive data and removed.

Yeah, this makes sense, added to the 6.0 todo list.
