Notwithstanding the other comments on context free vs sensitive, the 2014 article predates the language server protocol, which neatly moves the support for programming languages from the IDE to a stand alone tool tied to the language: https://microsoft.github.io/language-server-protocol/ https://microsoft.github.io/language-server-protocol/ https://en.m.wikipedia.org/wiki/Language_Server_Protocol https://en.m.wikipedia.org/wiki/Language_Server_Protocol So that IDE support point has become much weaker, if not moot.
