Not by that much. I managed to do recursive lookup of diversions in only 1 
pass and my ser.cfg has gained very little in complexity. And this small 
complication in ser.cfg is compensated by the benefit that you only have 1 
transaction through ser. If you route back to the proxy you will create 
chained transactions and there is a problem with them timeouts (among the 
others already mentioned). If you route more than 2 times back, then you must 
be very careful how you assign timeouts to your transactions, else the chain 
may break in the middle. Not to mention that you must very carefully design 
the whole chaining and assign the proper failure route for each transaction.
In the end I found that you must put more care in how you write ser.cfg when 
you route back and the transaction processing is more complicated and harder 
to follow.
