I found github.com/gorilla/context had been in maintenance mode, After some search of dependency for it.

I truly just find one place that uses the gorilla context, as follows:
https://github.com/gin-contrib/sessions/blob/master/sessions.go#L64

func Sessions(name string, store Store) gin.HandlerFunc {
	return func(c *gin.Context) {
		s := &session{name, c.Request, store, nil, false, c.Writer}
		c.Set(DefaultKey, s)
		defer context.Clear(c.Request)
		c.Next()
	}
}

even github.com/gorilla/sessionshad removed the dependency, so why we need to keep the dependency?
