As a beginner/intermediate level myself, I think new routing syntax, which is similar to flask is itself a major feature of the django 2.0. This really simplifies the url routing than the regex(which is lot powerful though). For simple projects of mine, it may well cover 60-80% of my needs, maybe more.
Indeed. The somehow clunky syntax for named groups in python re was (in my opinion) a big drawback with old style routing. I hope this new style gains traction.
