It's not a trend...I've seen it for decades. For example, in my heavy network consulting days you could tell when someone was studying to get their CCIE, because they'd implement something that's on the test, is technically correct, but almost no one would do in practice. Like "why in the world are they using IS-IS instead of OSPF like the rest of the world??". 95% of the time, it turned out the person who implemented it (who as often as not had moved on to their next gig) was getting ready for the IRP lab exam when they did it.
