RFC4459 does not propose tunnel fragmentation (i.e., fragmentation
at a layer above IP but below the transport protocol).

Tunnel fragmentation was first discussed in RFC2764, then later by
me in RFC5320 and in all of my subsequent writings, which is how
it found its way into GUE extensions.
Yes, RFC4459 suggests the possibility of fragmenting the inner IP packet,
but that is not possible if it's IPv6. Fragmentation with the encapsulation
doesn't have that limitation.
Thanks for the clarification.
