why is modification of the return path required?

It's only required when forwarding mail to a 3rd party
(or "to another ADMD" in email-arch terminolgy), as it
indicates the transfer of responsibilty as outlined in
RFC 821.

Preserving the spirit of RFC 821 without reverse routes
is a black art.  But ignoring it results in backscatter.
