I've been using this pattern for the past couple years for the benefits the author mentions. In addition to that, it can help with overly complicated functions (which, ok, could probably be refactored) that have multiple optional arguments.
My company just finished a several week review period of Greptile. Devs were split over the usefulness of the tool (compared to our current solution, Cursor). While Greptile did occasionally offer better insights than Cursor, it also exhibited strange behavior such as entirely overwriting PR descriptions with its own text and occasionally arguing with itself in the comments. In the end we decided to NOT purchase Greptile as there were enough "not quite there" issues that made it more trouble than worthwhile. I am certain, though, that the Greptile team will resolve all those problems and I wish them the best of luck!
i can only speak to my personal experiences and not the entire "Job Market" but i have seen qualified, competent team members let go during "positive transformations" and expectations that their workload will be covered by others while corporate crows about how using AI will be such a force multiplier for those who remain.
