It was never a good idea. It was a necessary evil (kind of like NAT in that 
regard) to expeditiously deal with a somewhat tenacious (at the time) problem 
which has since been given a significantly better solution, but so long as the 
workaround appears to be working, people are loathe to put in the effort of 
implementing the actual solution.

sigh… Human nature.
