Paper definitely identifies benefits for adding generics. This quote jumped out at me for its relevance to this discussion: "We observed parameterization of 1152 types, but actually found about 46 % of these types (532) only had exactly one type argument ever used throughout the project’s history, suggesting that needless or premature generification of objects occurs fairly frequently.We observed parameterization of 1152 types, but actually found about 46 % of these types (532) only had exactly one type argument ever used throughout the project’s history, suggesting that needless or premature generification of objects occurs fairly frequently." Put in the term of this discussion thread, the study notes that about 45% of the time (for the Java projects studied), portions of the code get harder to read, with little or no clear benefit. There's no basis for thinking that the same problems will or won't occur with any generics added to Go, but it seems like a reasonable place to point to for concerns driving this thread.
