Most of us would code shift when writing in other milieux, some weaned ourselves off the habit when our work started interfacing with nonreceptive readers, and a few retained the affectation to make a statement (or an anti-statement!).
It's amusing to see the style resurface in a new generation though. I guess it's no more odd than when 20 year olds unknowingly emulate the dress and mannerisms from when their parents were young. We just smile and recall the age when we thought we were being different too. :)
