First and foremost, I was surprised to find no reference to tunnel or MTU

This is discussed in detail, with some much more specific terminology, in draft-ietf-intarea-tunnels
In particular, *path MTU* is different from the received MTU, etc. It’s important to get this correct (note the many examples of current standards that do not).
