that's odd... routing is a DESTINATION based problem, not a SOURCE based one.
Routing has always been more than a destination based decision. Even in the beggining IP had LSRR/SSRR.
Sure, ip-options bits were/are allowed for LSRR/SSRR, which as you said below is disabled for a multitude of reasons on many/most/all (?) large parts of the Internet for many reasons, not the least of which is performance penalties. So, aside from the 2 examples routing ip has been a hop-by-hop destination based problem, source addresses (even with LSRR/SSRR I believe) has little to do with the equation. I could be wrong, I am just a chemical engineer. If this was a distillation column or a raction vessel I might be more sure :
