A note on the ESP SPI overloading trick, such as used in draft-ponchon-ipsecme-anti-replay-subspaces for which SSH has IPR, they submitted an IPR statement:
See https://datatracker.ietf.org/ipr/5880/ In the event that any claims of the Subject Patents are necessarily infringed by such future version of IPSec (“Essential Claims”), SSH agrees, upon written request from a party, to negotiate with that party a non-sublicenseable license to the Essential Claims under reasonable and non-discriminatory terms and conditions, taking into consideration the other technologies implemented in the same product, solely to the extent necessary to implement required portions of the Future IPSec RFCs, provided that the party grants a reciprocal license to SSH and provided that the license terminates if the party initiates a claim of patent infringement, directly or indirectly, against SSH, its subsidiaries, or its affiliates.
