[SR-Users] Steering egress on replies

Hi,

Happy New Year!

From what I understand, replies are always sent back out of the listener on which they were received, though `reply_to_via` (off by default) can override this and cause the exit listener to be recalculated based on a real-time assessment of the best way to reach the last Via hop.

Two questions arise:

1) If turning `mhomed` off, can `$fs` be used to override the exit interface of locally generated replies, too? If so, where should it be done? In a request_route prior to a send_reply() / sl_send_reply() / t_reply() call?

Or should it be done inside a local reply route or onsend_route?

2) Does this differ for locally generated replies vs. relayed replies, either statefully or statelessly?

Thanks!
