I don't use PCB, but there are a couple of good reasons to eliminate 
unwanted stubs:

1) they'll cause signal reflections, and so affect timing

2) if you're ever going to use the autorouter for IC layout, then 
stubs/antennas are bad news. You can get charge build-up on the wire 
during fabrication, which can potentially destroy transistors. These 
would have to be marked as violations and fixed.
