Does anyone have a bit of an inside view into what changed in the perspectives of the language maintainers?
I’m not buying the “it took us 20 years to understand how to do it correctly” argument, as this is something you explicitly take into consideration when designing the language or not. And it was specifically not a part of language design, and is much harder to retrofit (backwards compatibility).
So what changed?
The original maintainers moved on to other projects and the new community maintainers came to a consensus through the proposal and governance process.
Seriously, that's all it was. Just Ian alone proposed and rejected a half dozen of his own different approaches to generics. Finally a language + implementation plan came together that people all liked.
Nobody was ever opposed to generics that I saw.
