Btw, not to speak for Suckling, but in the past he's made comments to the effect that the whole modern-vs.-traditional question is... boring - I think was the word he used. His point seemed to be that the real issue is quality. I mention this only to point out that it's unlikely that he would ever draw lines such as these in an article.
For my own part, I find it fascinating. Most people (as evidenced here) use the botti vs. barrique as the yardstick (as it is clearly the easiest to track), but a case could also be made for a) degree of extraction, and b) clonal selection - both of which effect the resultant color of the wine. Valdicava is one that comes to mind which has made a conscious decision to plant clones that produce a darker color. Some (Galloni and IWC, to note) consider the dark color to be 'atypical' and therefore 'modern.'
I realize I'm clouding the issue, but I remember a list similar to this in which Daniel Fulton (if my memory serves me) labelled Fanti as "ultra-modern" for their use of barrique, but also due to the high extraction and dark color. This makes a lot of sense to me.
Even within the category of 'blends' (barrique and botti), the styles can be wildly different. Taste a Fuligni Riserva (quite delicate, floral, refreshing) next to a Silvio Nardi Manachiara (dark, viscous, and chocalatey), and you might be surprised that they're considered similar in the modern-vs.-traditional discussion. Again, sorry to complicate the issue, but I personally find it intellectually thrilling... not to mention hedonistically satisfying.
