If it isn't being taught, then that is a sad indictment of pilot training in this country.
At the risk of generalisation, there is very little pilot training in this country. Once a pilot has passed his CPL and instrument rating and is looking for his first job, then it becomes up to him if he wishes to increase his professional knowledge. In the world of general aviation he learns on the job. Few employers have the time and financial resources to train him any more than he has already studied for in his licences and ratings.
There are some pilots who now rest on their laurels and deign to study any more than is absolutely necessary to keep their job. That probably applies to the majority.
