Thanks for the link to the OCTO-008 (at https://www.icann.org/en/system/files/files/octo-008-15apr20-en.pdf) file. 
 However, it doesn't say its a non-issue. Under 3.1

"The Chromium queries are the largest single cause of queries to root servers. Other IMRS instances often see over 50% of all incoming queries from Chromium. The purpose of these queries is to check if Chromium is behind a captive portal. Provisioning for root servers is often a function of the overall load on root servers to satisfy the scaling needs. While these queries are free for Chromium to make, the cost of provisioning for root-server instances is not. Google has been notified of this issue, but it remains outstanding."

Matts APNIC blog describes exactly what they are for…

And no these are not any kind of attack on the root, the Ars article blows it out of all proportion, OCTO presented on this at some stage earlier in the year and its also mentioned as a non issue in OCTO-008 https://www.icann.org/en/system/files/files/octo-008-15apr20-en.pdf

I'm still left with little understanding of why this is important?

 

What is the use of these lookups for the browser? A previously undisclosed security feature? 

 

And what is being alleged from the name service side? A unintentional DOS-type attack on the root server system itself? 

 

CAS.

The Chromium browser—open source, upstream parent to both Google Chrome and the new Microsoft Edge—is getting some serious negative attention for a well-intentioned feature that checks to see if a user's ISP is "hijacking" non-existent domain results.

The Intranet Redirect Detector, which makes spurious queries for random "domains" statistically unlikely to exist, is responsible for roughly half of the total traffic the world's root DNS servers receive. Verisign engineer Matt Thomas wrote a lengthy APNIC blog post outlining the problem and defining its scope.

Not aware if this is  mentioned before  in ICANN circles
