I hate on 11t cogs for their chordal action inefficiency...
So do I, but we're howling in the wilderness. Track riders have only just come around to using big sprockets, and they only have one to worry about.
I guess when the manufacturers have sold everybody 1×10T-50T, there will be a miraculous "discovery" of science and they'll try to sell everybody 3×14T-28T again. Probably 15-speed cassettes so at least we'll get back our true straight-through clusters 😀

I hate on 11t cogs for their chordal action inefficiency... 10t and 9t are far worse.
Not to mention the fact that it makes for even wider jumps between gears, right where you're fighting the wind almost entirely, which resists with the cube of your speed.
You want smaller gaps at speed, but they keep making them bigger! Such poo.
The only way around it is bigger cogs and more chainrings. Instead of continuing to worsen the dish on rear wheels and make chains thinner, we could have all the range we want, nice and close, if only road triples were still a thing.
I even came up with another possibility, using 38/50/52 rings (due to the maths, that's about the only good choice for this) for a half-step setup.
It can use a double crank; the 38t only needs to be inboard of the standard inner position by a mm or two, while the 50/52 is probably best made as a single part, with a narrow gap between them, centred on the standard big ring location. FD could be the same as a double one, but would require a specific cage (the extra travel is within normal adjustment range).
Of course, it'd only make sense as electronic.
