@martinthomson Yeah, my train of thought as a server stack developer that happens to also work as a client was that I might be interested in having a pre-built XOR mask on the server-side. Then, I might expand that constant vector to the 1,200 bytes, and use it for decoding the Retry packets too.

That said, I do agree that not all stack developers would (think and) actually implement that way. So I agree that there's some value in encrypting the token rather than just applying GMAC, at the cost of as small as requiring XOR on the server-side.
