first: yes, unlike synaptics, libinput could support this since it'd be nicely hidden away in libinput, only apply to specific models, etc. what I'm more concerned about: if it's 4 years later - how many devices still have that functionality? I'm hesitant to add a feature that only works on laptops that have been discontinued a significant amount of time ago.
