Not questionable? I'll use a more obvious and illustrative example. Going from 10 to 11 speeds. In terms of objectively measured things - like gearing range and tightness - gains are very questionable. Price however, is clearly higher for 11 speed gearing. That's good for the manufacturer, while it's worse for the buyer. Gain nothing - pay more. But one believes they are "upgrading", or "future proofing" (my personal favourite), etc.

That's what I meant when I confirmed that many new things in cycling are more marketing, than real improvements. That's the way it is, whether you like it, or are even aware of it, or not.
