I don’t know whether it was ever effective strategy for candidates, but I will simply say that as a hiring manager for over 12 years, I have never been interested in anyone’s resume when I see that.
Most applicants have no idea about your internal HR procedures and what's the pipeline before the resume even gets from you so they might as well optimize for what generally seems the most "successful" approach. Maybe they actually think writing metrics and keywords is a good idea, maybe they think its stupid and resent it but can't get any interviews without it, its really impossible to tell without other variables..
For my own resumé, I include the stack used at each job which I feel strikes a fair balance.
