That bit about search using the ripgrep plugin not providing context has always been available using telescope and a handful of clone plugins.
There are other things too, like pressing `*` then using `:%s` is no different than the behaviour they describe. I use a plugin that shows you all the updates live as you type making it essentially the same as multiple cursors (for this example). The only difference is that you're typing on the command prompt as opposed to the current line.
