I've never been a big fan of any such language, regardless of layoff context. Do enough people prefer it that it's actually a net win for business by way of improved morale or whatever? I wonder if it's been seriously studied.
Then again, I'm also of the mind that email addresses (or whatever other contact methods) ought to belong to functional areas/positions rather than to people (other than for person-specific topics such as time off, personal development, etc.) so turnover doesn't lead to questions of where to send questions/requests. I assume this is an unusually inhumane outlook!
