Thanks for supporting the project, @balthazar. I agree with what you mentioned. For example, Sparrow Wallet relies on mempool to suggest the user’s fee rate. Of course, the user ultimately chooses, but the displayed data is still based on that same rounding logic. Even so, from what I see, the UX they use is quite limited in resources, which in a way makes it better than mempool’s, because it does not push the user into three fixed choices: economy, normal, and priority.
