I will take a more serious look at your patch; at first glance I'm not
sure what it does differently.

"Senders" is not going to be helpful for choosing a smarthost on a
router that is used to verify senders. The whole point of verifying a
sender is to check that you can send a bounce message to that sender.
Therefore, the routers should be (and, since 4.32 are) run with
sender=<> when verifying senders.
It sounds to me as if you have a complicated setup where using the same
routers for actual sending and for verifying doesn't work well. You can
make use of no_verify and verify_only to set up completely different
routers for the two cases.
