That doesn't follow. See below.

The draft mitigates a known problem with communication paths that
do not include nested tunnels requiring nested fragmentation,
where the nested tunnel has to deal with an MTU <1280 *and* where
the nested tunnel goes through a firewall that wants to analyse
the complete header chain of the innermost packet.
No, I don't think it's worth considering that case before specifying
this mitigation.
