"Makes it easy" if you live in an Internet with a number of routes
significantly less than the limit imposed for having stable RPF enabled
on your devices, or have devices without bugs in RPF checking when said
limit is spotted vaguely across the horizon.
I dont seem to be in either of those places. (Although I have not
sacrificed a router in the last upgrade version or two to see if things
have improved.)
