people dont read comments.  that method of deprecation is pure wishful 
thinking.  people forward porting old code (boards/drivers/whatever) or even 
writing new code will build it up and if it seems to work, submit it.  and no 
amount of review is 100% all the time.  if, instead, they got a build error 
straight up front, they'd sure as hell figure out why and get it fixed.  this 
is where a comment in the struct that says "this is legacy, do not touch, go 
read README.macaddr" would actually be read and be useful.
