With respect to BGP MD5 at least, a shared key is required, so you can't 
make it "default".

As for why its not more commonly used... Despite all the whining about the
potential for an attack, I'm not aware of anyone having actually done so.  
Routers are notoriously under-CPU'd, and I think most engineers would
rather have routes converge 30% faster than protect against an attack
noone has ever done.

That and its just one more thing to negotiate with the other side. :)
