I am thinking about the case when a mobile router A provides an access
link for a mobile router B, which provides an access link for a mobile
router C, which provides an access link for a mobile router D, etc.
Each mobile router would coordinate with their home networks so that
there would be tunnels-within-tunnels-within-tunnels-etc.

I can think of use cases related to my industry, for example when a
first airplane provides an access link to a second airplane, the second
airplane provides an access link to a third airplane, etc. I think this
might come up also for certain mobile ad-hoc scenarios.

In any case, however, whenever there is a fixed or mobile node connected
to an access link provided by a mobility anchor there is nothing stopping
the node from setting up a tunnel. Then, there will be at least one
tunnel-within-tunnel nesting.

Thanks - Fred
