The short answer is that there simply isn't a good reason to do this on 
a modern system, and there is no volunteer to donate the enormous amount 
of effort required to make something work for which there isn't a good 
justification for expending that effort. There should be no flamewar, if 
someone wants the situation to change they simply need to be the person 
who puts in all the work.
