Switching from libinput to evdev

A few weeks of experimentation with libinput led me to believe that many of its advanced mouse-related features are not (yet?) implemented. Most importantly to me, you cannot block the mouse wheel with it, nor can you emulate the mouse wheel system-wide with the middle button. My question is twofold:

1. Would it make sense to switch my Ubuntu from libinput to evdev? Am I going to lose anything important, either immediately or in the long run?
2. If there are no apparent disadvantages to this course, how should I go about it? apt lists dozens of packages for both, some labeled hwe and some not. What should I remove and what should I install instead?
