I think the point isn't asserting that it isn't new, rather it is a sad state of affairs that many tools are still playing catchup with developer tools of the 80's.
For example, every time we discuss Lisp on HN, many talk about SLIME, SBCL and such.
Yet, the actual modern experience of what it meant to use Lisp on its glory days lives on Allegro Common Lisp and Lispworks.
Reading papers from Xerox PARC research always makes me sad that many think replicating a PDP-11 is the ultimate developer experience.
