That's still a silly point. For security reasons a lot of people don't hook their source control directly into production web-servers, and instead deploy from a secured environment hooked into secure control onto production (which would still require something like e.g. SFTP for the actual transfer).

Regardless their point was poorly explained/explored.

Correct, workflow. Even with the tools themselves, rather than "best practice" it seems mind boggling using SFTP within the editor. With things like SASS, bower, grunt, npm and the like - it doesn't even seem like it'd be compatible.
