The stated reason was an ideology that someone might misuse it to 
sneak semantic info into comments.

The compiler implementation also discards them unless you use the 
-D switch, but that'd be fairly easy to fix (or even letting it 
stay blank unless you passed the switch would probably be 
acceptable too) so implementation shouldn't be a big deal, but 
then we're told that'd increase memory usage and compile times. 
Cuz I'm sure some text comments are a big concern.

Yeah, or even just pulling in for for wrapped script languages, 
auto-generated command line help or web site forms. Lots of nice 
little things.
