No, people celebrate terse writing fairly non-stop. It may only intersect with your awareness every 4-5 years, but its not like it goes away in between.
I don't think this is presenting terse writing as a new insight. The innovation here is (if I'm understanding it correctly) using a grammar parser to identify some fairly complex criteria (e.g. avoiding left-branching sentences).
Every 4 or 5 years everyone celebrates terse writing like it's new.
FTFY.
