I think it is important to remember that this draft is about *IP* layer fragmentation. Tunnels can employ tunnel-layer fragmentation at a layer above IP:
https://datatracker.ietf.org/doc/draft-ietf-intarea-gue-extensions/ https://datatracker.ietf.org/doc/draft-templin-intarea-grefrag/ Or, if the draft intends to also cover tunnel-layer fragmentation it should probably be updated to say so.
