I understand the pragmatism behind having or not features in the language and its standard library. But, almost all the golang projects I've worked with implement their own utility function to remove elements from a slice, sometimes with order in place, others not. Mostly always these home-brewed libraries ignore bounds-checking introducing runtime problems if the user is not careful enough.
That said, when a feature becomes a ubiquitous necessity across so many codebases, I believe it should be considered to have a standard implementation.
