I didn't read the original message carefully enough, my apologies.

I took "around the failures" to mean from one point within an ISP to another
point with the same/a different ISP.

Tunnels can fix some types of failures, but they can't fix every type of
failure, like routing problems that affect the entire ISP. This kind of
multihoming is clearly inferior to the regular IPv4 way.
