Go accepts a policy for retiring GODEBUG flags, targeting 1.27

The accepted proposal to formalise how GODEBUG flags get decommissioned lands as the day's most consequential item, with Griesemer opening an umbrella issue targeting Go 1.27 to pay down a growing pile of compatibility knobs. It pairs neatly with the older ExecuteFuncs proposal finally being accepted for text/template and html/template, so the standard library is quietly tidying two different corners at once. Elsewhere, a post on reusing Go's tooling and standard library as the basis for a systems language is the more interesting read, and someone got tired enough of hand-editing Caddyfiles to build a lazygit-style TUI for it, which is a reasonable use of an afternoon.
