upstream Linux network maintainer noted:

basically rp_filter=1 makes no sense on leaf nodes.  if your system does no routing, then it shouldn't have that knob set.  we should flip it off by default and leave it to people who actually building routers to manually enable it.

it was turned on in 2004 by virtue of "it's what Redhat is doing":

This will be commented out by default in Baselayout-2.3, so you will
need to enable it if you need it.
