Ok, thanks for the clarification. I wonder if there are situations in big teams in which one team that uses generics can take a look at a large Go codebase within the same company and see what they think? They must have received such feedback at Google, surely?
There's at least one high profile example: the standard library itself. It must have been obvious by the time they designed the standard library, before the language was out. They had to have feedback then, just look at the trail of rage against the absence of generics.
They ignored it then —I have no idea why. I'm not sure they'll listen now.
