From what I could tell, they specifically worked out the current design in a way that allows them to change the implementation later. The current WIP code, as far as I know, mostly just compiles Generic Go code into the regular Go code, so closer to the “slow compilers” method, but the eventual goal seems to be some form of a hybrid approach[1]. EDIT: Here[2] is a direct link to what seems to be the most recent public DRAFT of the design document of the hybrid approach in question.
