Well, we have already defined seven extensions to GUE. AFAICT adding these was quite straightforward none of these can break forward compatibility, nor NIC offloads, and is amenable to efficient header parsing in both software and hardware. GUE also allows for private data in the header section for a site or application to insert data with whatever format is suitable (for instance, if SPUD uses GUE format CBOR data could go here). But, if you really do see an deficiency in this model that would "tie your hands" please elaborate, we appreciate the feedback!
