CL 555597 - optimizes TypeFor (added in accepted proposal https://go.dev/issue/60088) for non-interface types; doesn't seem to need a release note
a few x/tools CLs deprecated and deleted the experimental golang.org/x/tools/cmd/getgo tool per accepted proposal https://go.dev/issue/60951; an unreleased change and not something that's in scope of Go 1.23 release notes
