Though maybe not the typical case you could start creating spans for user workflows and compare the time it took to do workflow A vs alternative workflow B (in A/B testing). Or you can simply use metrics to collect usage information like how many times a certain action is performed in your system which may tell how popular it is. I didn't think to much on this but I played with it once in a hackathon and made a tool that showed how one customer site performed versus another customer site by showing performance comparisons on workflow spans and augmenting this information with metrics of most used tools to get an indication if the other site was maybe faster because it used different parts of the product to perform certain actions faster.
