For example, one could think of referring interested readers to:
MTU and Fragmentation Issues with In-the-Network Tunneling

But I don't even know if that is the more appropriate text one would want
to point at.
I'm cc-ing the author, Pekka Savola, as he may have some more current info
for us.
In developing a protocol, I personally think the protocol specification
should decide a model to be adopted either in the protocol or in operating
the protocol, or just explicitly leave the issue open. RFC4459 just lists
some alternatives and their tradeoffs.
Apart from that there isn't much to add. There's a bit more recent 00 draft
that also discusses tunnels from an architectural and less practical
perspective, but I'm not sure if it provides any more information than the
RFC above: draft-touch-intarea-tunnels-00.
