On a second thought: I start thinking it doesn't make much sense,
especially given the current context of self-tests, to explicitly test
this, because it's a rather particular corner case.

I think it would make more sense to introduce generic tests first.
About, say, PMTU, or route exceptions, but not "tunnel causes route
exception and administrative change doesn't affect PMTU".
