I absolutely love this approach to feature inclusion and usability. User research showed that for some number of users (presumably not the majority) this is a familiar and comfortable interaction. All too often we see companies cut features (or whole products) because the metrics/analytics indicate most users don't use them - ignoring the fact that those features may be really important to the small minority.

I understand that every feature and product carries a maintenance burden, but I believe that the barrier to cutting them should be really high (especially when users build workflows around them).
