I don't understand because I'm not a developer. I could understand that
synaptic was written in a confusing and complicated way, but his behavior is
better then libinput.
You have your reason from developer point of view, but I'm not a developer. I'm
a user. I don't care about code. I care about things work on my system in a
good and comfortable way.
libinput works, but it's not comfortable. And it's less customizable. I can
only set the acceleration speed (that's even broken on Plasma desktop, but I
know that's KDE developers fault). If I set it higher, the pointer is too
reactive. If I set it lower, the pointer is good for short movements, but not
for large ones. If a find the right value in the middle, the pointer is good
for large movements, but not for short ones. And I can't even disable the
acceleration. 
I thought updates was an improvement, but I don't see any improvement moving
from synaptics to libinput.
I would not even care about that issue, but synaptics became deprecated and in
the future it will not work with further updates (especially on Arch Linux
since it's a rolling release distro). So I'm not really free to use synaptics
because libinput is the default supported touchpad driver and sooner or later I
have to use it permanently.

Please, don't take these words like an offense, I'm only trying to explain my
point of view.

Are you saying my touchpad has only "accelerated profile"?
I don't remember (I'm using libinput now because I'm trying to get used to its
behavior) but I'm pretty sure that I could disable the acceleration on
synaptics. Even on Windows by Synaptycs proprietary driver.
Maybe I'm wrong but I think my touchpad could work without acceleration, so it
seems more a libinput missing feature.

Don't know how to do and, as I said before, I'm not a developer. :(
