I can revert to the old behavior. I asked for feedback and

none at the time ...
I would like to see it working, but working correctly. If it is not
possible to implement it correctly - then reverted, or at least
disabled
by default.
Asking for compatibility is reasonable but the existing packet
leaking behavior is incorrect.
After reviewing the previous thread on this topic back in July,
I see that Henri Hennebert requested this feature for IPv6.
I intend to introduce a sysctl variable to control whether loopback
route should be installed for the local end point. By default
the old behavior maintained.
What about only adding the route if it does not exist yet? That should
handle the common case of reusing your ip address on the ethernet
interface on the local side of point-to-point links.
the hard part is removing it if it is the last interface that uses it.
