Even though it's been a long time since I learned about BGP, one would 
expect that the best route there is the best route back at any given 
time.  So any asymmetric link would definitely be less efficient than it 
could be, right?  Is there a reason at the BGP level that the best route 
there wouldn't be the best route back?

I say no, but maybe out of ignorance.  I consider it a question that 
needs to be justified... we don't need a "why not" to justify 
weights--it's assumed that weights will provide information about the 
best network to take.
