No, but the providers who provide those connections should be multihomed.
If they're not, I'd consider switching providers. Simple as that.

multihomed to whichever parties decide to generate split ups on purpose
in the intarrwebbz.. meaning: all of them.. (you can never tell which ones
will get the idea to depeer next, so you have to be multihomed to all of
them or this can still happen)

I am afraid you are confused. No, you do not have to attach to every network unless you think every network is going to disconnect from every other network simultaneously. (Would there even be an Internet then?)

If you are attached to two transit-free networks, you are guaranteed connectivity to the entire Internet unless there is more than one bifurcation simultaneously. And not just any two bifurcations. Specifically, both of your upstreams would have to depeer the same transit free network at the same time.

Attach to three, and it would require all 3 to depeer someone simultaneously to affect you.

Etc., etc.


what should happen here is their customers just enforcing a contract
change that they contractually have to make every possible effort to peer with
anyone or the customers leave...

Good luck with that.
