Actually, usenet posts were not distributed via source routing. They
were exchanged with neighboring sites. The "bang paths" that were
generated as a result of a post making its way through usenet were
used by uucp mail as a reverse path to the original poster.
Path rewriting (using programs such as pathalias) came into play as
more optimal routes were able to be computed using the connectivity
data from uucp maps.
