Yeah seems likethe business interests have overridden the adpotion needs. Knowing the IETF process is molasses slow , they still have not made moves to close that gap.For open source at least a implementation RFC that interested parties could work with - none avaiable.

They want to sell a technically brillant protocol that is single vendor propriety/patent restricted.

Their bet should have been of open protocol and captalizing on fist mover advantage to drive their business side witha large partner like ericsson/cisco etc.

Of course theres also the soveriegnity angle knowing what went on with another swiss company CryptoAG.
