Those were not invented by Sublime. Lots of older editors have those things, including TextMate and even GNU Emacs and XEmacs. XEmacs had a package manager since the early 1990s.
What Sublime has going for it versus these other editors is ease of use and a much better looking UI. But VS Code has that too, and it's free.
