Haven't read the article but I used to develop a kiosk application that used headless Chrome and holy fuck is that a complicated endeavor. It wouldn't be if browsers were content to simply be browsers, but Chrome has so many stupid value-adds and telemetry points that care+feeding of the Chrome (later Chromium) instances took up a substancial part of my job. At one point we toyed with a simply pyGTK app that loaded a webview but there were issues with that as well. The browser space really needs to return to its roots.
