You seem to be under the misconception that addresses belong to

ifconfig(1) associates addresses to interfaces.

Right, and then that address belongs to the machine.

In the weak end system model. In the strong end system model the
address belongs to the interface.

If you configure an interface to one address, it's won't accept
packets addressed to other (unicast) addresses.

It will under Linux and under any system using the weak end system
model. It will not (for local delivery anyway) on a system configured
for the strong end system model.

Yes, it will. IP would not work if that was the case, you could
never have a functional router.

There are routers, there are end systems. While the two may coexist
within the same *** metal, they are still separate concepts.
Accepting a datagram for local (ie within the machine) delivery would
follow the rules for "end system." Accepting a datagram for
forwarding presumably would not follow the rules for "end system."
