I agree. Now that people got over the sticker shock of a 2200 dollar 50mm lens and a 3000 dollar 28-70, time to address the less sexy but ever so important "boring" segment. Sub 1K USD primes that don't aim to take some f/stop crown and cost upwards of two grand for a common focal length are a good foundation. Ditto the wedding/portrait bread and butter 2.8 zoom trinity. And various f/4 zooms, and a few wide options for landscapes...in other words not that different from this:

sprinkle a specialty lens as well as your obligatory variable aperture "budget" 70-300 zoom or whatever here and there.
Canon should release a roadmap like above. Some worry it "gives away" their plan. What plan? Nikon leaves the slot blank when it doesn't want to tell you as can be seen by those blank empty slots in 2020-21. And when they do tell you, it is a 100% predictable necessary lens: 2.8, f/4 zooms, and 1.8 primes precisely like CR Admin's list. Any competitor that cannot anticipate these lenses isn't much of a competitor. And even a 2 minute search for patents in NR reveals some of those "secret" lenses
52mm f/0.9 and 36mm f/1.2 (will probably be labeled as 50 and 35 for marketing purposes)
