## AI overview

This article examines Go's two-year effort to move its HTTP/2 implementation from golang.org/x/net/http2 into the standard library. It explains the legacy architecture, the maintenance problems it created, and how the work was divided into 11 independently deliverable tasks. Go 1.27 completes the migration and makes the external package a compatibility wrapper.

## Source excerpt

Go 语言自 2016 年（Go 1.6）便透明支持 HTTP/2，但其实际实现却在外部仓库 golang.org/x/net/http2"寄养"了整整十年，带来了安全补丁倒灌繁琐、无法原子化改动、配置割裂等沉重技术债。随着 Go 1.27 正式发布，历时两年的跟踪计划 #67810 终于圆满收官：11 个子任务彻底打通，HTTP/2 实现正式回归标准库核心（net/http/internal/http2），原外部包反转为兼容外壳。本文全景拆解这场经典的大型存量系统重构实践及其带给开发者的原生红利。
