I think you are taking this way too personally. Of course, pro teams will continue to pursue marginal gains with a 12-speed groupset. And they may run larger, custom chainrings as a result.
I’m just saying I haven’t heard of that and that I am not sure this is an apt description of what is happening. The reason pro teams run 11-speed drivetrains with a 54/44 chainsets at times are AFAIK marginal gains, and they spend very little time in, say, 54:11, because that gear is too tall even for pros in most situations. But you wouldn’t portray that as “pro teams run an 11-speed groupset as a 10- or 9-speed groupsets.”
