YMMV depending on your operating system.
If the old address is removed, then TCP sessions established with the old address as an endpoint will break; hence plumbing TCP sessions to loopback addresses is not a solution to TCP survival over renumbering attempts.

That was my point.

You can solve the renumber thingie by having all TCP connecting to/from
an official IP on the loopback interface. Then the routing code could
do its work and route the packets through some some other or renumbered
interface.
So how do you renumber the loopback interface?
